Understanding Strongly Recommend vs. Highly Recommend helps you choose the right phrase for clear, natural, and confident professional communication. Choosing the right recommendation phrase can change how your message sounds and how readers feel about it. Strongly recommend and highly recommend are similar expressions, but their tone, intensity, and natural usage can create small differences in meaning. This common confusion appears in English writing and speaking, especially among English learners who are unsure which phrase sounds better. Writers, professionals, educators, and native speakers may also notice how these expressions affect professional and natural communication. At first glance, they can seem identical, yet small word choices influence reader perception, clarity, precision, and overall communication. In emails, reviews, workplace communication, social media posts, and everyday conversations, the context matters.
Highly recommend often gives a very positive recommendation, while strongly recommend can express firm advice or personal insistence. Both phrases can support a positive opinion, although the intended meaning, expression, and purpose should guide your choice. In professional-writing and academic contexts, the difference becomes clearer through textual-analysis, semantic-distinction, and language-precision. For example, a professional review may say, “I highly recommend this movie,” while a friend giving direct advice may say, “I strongly recommend this book.” Both phrases are grammatically correct, so neither is wrong. The proper phrase depends on the intended tone, audience-awareness, context-awareness, and reader understanding. In formal writing, informal writing, casual writing, and professional-context situations, clarity, accuracy, effectiveness, and confidence remain important. Tables, examples, demonstrations, case studies, real examples, real-life examples, real-world scenarios, examples-of-usage, and structured-examples can make these distinctions easier to understand. Following guidelines, instruction, best-practices, correct-usage, editorial guidance, professional-guidance, instructional-practice, instructional-guidelines, and editorial-guidelines can strengthen writing-skills, communication-skills, and writing-quality.
A useful guide can breaks down the subtle-difference with clear explanations and practical tips, helping you see what works best for each audience. Practical usage tips, observational-analysis, reading-analysis, textual-clarity, knowledge-building, clarity-principles, accuracy-of-expression, precision-of-meaning, expression-clarity, clarity-of-expression, and communication-accuracy can improve your writing-practice, confidence-building, professional-insight, audience-impact, semantic-insight, and learning-practice. A writer can then make each recommendation more impactful, precise, and trustworthy. For English learners, the same meaning may still cause confusion, but a simple example helps: you can tell someone that a restaurant is a very good choice, highly recommend a service, or strongly recommend a course when offering personal advice.
Let’s dive in!
Quick Answer:
Both strongly recommend and highly recommend are correct.
Use strongly recommend when you want to emphasize the force, importance, or seriousness of your advice.
Use highly recommend when you want to emphasize strong approval, quality, or a very positive opinion.
| Phrase | Main idea | Typical feeling | Example |
| Strongly recommend | Firm advice or emphasis | Serious, emphatic | I strongly recommend backing up your files. |
| Highly recommend | Strong praise or approval | Positive, enthusiastic | I highly recommend this restaurant. |
The difference becomes clearer when the recommendation involves an action.
I strongly recommend that you arrive early.
This focuses on what the reader should do.
Now compare it with:
I highly recommend this restaurant.
This focuses more on how good the restaurant is.
Still, don’t treat the distinction as a rigid rule. “I highly recommend this restaurant” is completely natural English. Cambridge itself gives examples such as “I highly recommend this restaurant” and “I would highly recommend her” in its dictionary content.
What Does “Strongly Recommend” Mean?
Strongly recommend means to give a recommendation with considerable force or conviction.
The basic verb recommend already means that you suggest something because you consider it good, suitable, or appropriate. Cambridge also shows that recommend can introduce an action, such as recommending that someone do something.
Adding strongly increases the emphasis.
For example:
I recommend that you save your work regularly.
This sounds like ordinary advice.
I strongly recommend that you save your work regularly.
The second sentence sounds more serious. The speaker wants the reader to pay particular attention.
What “Strongly Recommend” Emphasizes
The phrase can highlight:
- Importance
- Firm conviction
- Serious advice
- A strong preference
- A warning
- A recommended action
That’s why the phrase works especially well when someone needs to make a decision or take an action.
Examples of “Strongly Recommend”
- I strongly recommend reading the instructions first.
- We strongly recommend arriving at least 15 minutes early.
- I strongly recommend reviewing the agreement before signing.
- The safety team strongly recommends wearing protective equipment.
- I strongly recommend backing up your important files.
Notice a pattern. Many of these sentences tell the reader what to do.
That doesn’t mean strongly recommend only works with actions. You can also say:
I strongly recommend this book.
The sentence is grammatical and natural. The context simply determines whether the phrase sounds like firm advice or strong approval.
What Does “Highly Recommend” Mean?
Highly recommend generally expresses a very favorable opinion.
It tells the reader that you think something is particularly good, useful, enjoyable, or suitable.
Cambridge specifically lists highly recommended as meaning that something has an excellent reputation. Its examples include a wine that “comes highly recommended.”
The expression also appears naturally in active sentences:
I highly recommend this book.
We highly recommend this service.
I would highly recommend her for the position.
These sentences communicate strong approval without necessarily creating a sense of urgency.
What “Highly Recommend” Emphasizes
The phrase often highlights:
- Quality
- Approval
- Positive experience
- Reputation
- Enthusiasm
- Suitability
You’ll often see it in reviews, testimonials, personal recommendations, and professional endorsements.
Examples of “Highly Recommend”
- I highly recommend this book to new writers.
- We highly recommend this hotel for families.
- I highly recommend trying the pasta.
- She comes highly recommended by several clients.
- I would highly recommend this course to beginners.
The phrase can also describe someone’s reputation rather than simply expressing the speaker’s personal enthusiasm.
For example:
She comes highly recommended.
This suggests that other people have spoken very positively about her.
That construction is especially important because “highly recommended” can carry a reputation-based meaning.
Strongly Recommend vs. Highly Recommend: The Core Difference
The easiest way to understand the difference is to ask one question:
Are you emphasizing the recommendation itself or the positive quality behind it?
Strongly recommend often puts more weight on the recommendation as advice.
Highly recommend often puts more weight on the positive assessment.
Think of the difference as two spotlights pointed at slightly different places.
Strongly shines a brighter light on the force of the recommendation.
Highly often shines a brighter light on the degree of approval.
| Feature | Strongly Recommend | Highly Recommend |
| Grammatical form | Adverb + verb | Adverb + verb |
| Basic meaning | Recommend with strong emphasis | Recommend very positively |
| Common focus | Advice or action | Quality or approval |
| Tone | Firm, emphatic | Positive, enthusiastic |
| Warnings | Very natural | Less typical |
| Reviews | Natural | Extremely common |
| Professional writing | Natural | Natural |
| Personal recommendations | Natural | Natural |
| Always interchangeable? | No | No |
| Often interchangeable? | Yes | Yes |
The distinction is one of usage and nuance, not a simple right-versus-wrong grammar rule.
Is “Strongly Recommend” Correct?
Yes. Strongly recommend is completely correct.
Here, strongly functions as an adverb modifying the verb recommend.
The structure is straightforward:
strongly + recommend
For example:
I strongly recommend checking the details twice.
You can also use it with a clause:
I strongly recommend that you check the details twice.
English commonly allows recommend to take a that-clause or an -ing form. Cambridge gives examples such as recommending that someone get more exercise and recommending writing feelings down.
Natural Patterns With “Strongly Recommend”
Strongly recommend + noun
I strongly recommend this guide.
Strongly recommend + -ing
I strongly recommend checking your settings.
Strongly recommend + that-clause
I strongly recommend that you check your settings.
Strongly recommend + someone/something for a role
I strongly recommend Maria for the position.
The exact structure depends on what you’re recommending.
Is “Highly Recommend” Correct?
Yes. Highly recommend is also completely correct.
There is sometimes a misconception that “I highly recommend” is grammatically wrong. That’s not supported by actual English usage.
Cambridge provides active examples containing highly recommend, including sentences about recommending a restaurant and recommending a person for a particular role.
For example:
I highly recommend this restaurant.
I highly recommend this course.
I would highly recommend her for the position.
These are standard, natural constructions.
Natural Patterns With “Highly Recommend”
Highly recommend + noun
I highly recommend this book.
Highly recommend + -ing
I highly recommend visiting the museum.
Highly recommend + that-clause
I highly recommend that you try it.
Highly recommend someone
I highly recommend him for the role.
So there’s no grammar problem with the phrase itself.
Can “Strongly Recommend” and “Highly Recommend” Be Interchanged?
Often, yes.
Consider:
I strongly recommend this restaurant.
and:
I highly recommend this restaurant.
Both sentences tell the reader that the speaker thinks the restaurant deserves a recommendation.
The second may sound slightly more like enthusiastic praise. The first can sound a little more emphatic. Yet neither sentence is inherently wrong.
This overlap matters because language rarely behaves like a mathematical equation. Words carry tendencies, associations, and context-dependent meanings.
English-language discussions also note substantial overlap between strongly recommended and highly recommended, while identifying contexts where their meanings diverge.
When the Difference Becomes More Noticeable
Compare:
I strongly recommend that you leave early.
This sounds like firm advice.
Now try:
I highly recommend that you leave early.
This is still grammatical and understandable. However, strongly may sound more natural when the speaker wants to stress urgency or importance.
Now reverse the situation:
I highly recommend this novel.
This sounds perfectly natural for a review.
I strongly recommend this novel.
This also works. It simply puts slightly more force behind the endorsement.
When to Use “Strongly Recommend”
Use strongly recommend when the recommendation carries extra weight.
For Firm Advice
If you want someone to take a particular action seriously, strongly recommend works well.
I strongly recommend saving a copy before making changes.
The phrase tells the reader that the advice isn’t casual.
For Warnings
The expression can also introduce advice against an action.
I strongly recommend against sharing your password.
We strongly recommend that visitors avoid entering restricted areas.
Here, strongly helps communicate seriousness.
For Professional Guidance
You may encounter the phrase in workplace, technical, academic, or safety-related communication.
Examples include:
- I strongly recommend reviewing the report before publication.
- The team strongly recommends testing the update first.
- We strongly recommend keeping a backup copy.
- The instructor strongly recommends completing the practice exercises.
The phrase doesn’t make the recommendation mandatory. That’s an important distinction.
Strongly recommended still means recommended. It doesn’t automatically mean required.
When to Use “Highly Recommend”
Use highly recommend when your main goal is to express strong approval.
For Reviews
The phrase fits naturally into reviews of:
- Books
- Movies
- Restaurants
- Hotels
- Products
- Courses
- Apps
- Services
- Travel experiences
For example:
I highly recommend this restaurant for anyone who enjoys fresh seafood.
The focus is clearly positive.
For Personal Endorsements
You can use highly recommend when recommending a person, service, or professional.
I highly recommend Sarah for the position.
I highly recommend this photographer for weddings.
The expression communicates confidence in the person or service.
For Positive Experiences
If something impressed you, highly recommend often sounds natural.
I highly recommend taking the walking tour.
I highly recommend this course if you’re learning graphic design.
The recommendation feels enthusiastic without sounding like an order.
Strongly Recommend vs. Highly Recommend in Formal Writing
Both expressions can appear in professional writing.
The choice depends on the message rather than formality alone.
Consider a workplace email:
I strongly recommend reviewing the proposal before the meeting.
This sounds firm and practical.
Now consider a professional reference:
I highly recommend Daniel for this position.
That sentence sounds like a strong endorsement of Daniel’s suitability.
Neither phrase is automatically more formal.
| Situation | Natural Choice | Why |
| Reviewing a contract | Strongly recommend | Firm advice |
| Recommending an employee | Highly recommend | Strong endorsement |
| Safety instructions | Strongly recommend | Serious emphasis |
| Product review | Highly recommend | Positive evaluation |
| Course recommendation | Either | Depends on intended tone |
| Restaurant review | Highly recommend | Enthusiastic approval |
| Technical advice | Strongly recommend | Important action |
| Job reference | Highly recommend | Positive professional endorsement |
Strongly Recommend vs. Highly Recommend in Reviews
Reviews are where highly recommend appears especially naturally.
Suppose someone asks about a new restaurant. You might say:
I highly recommend the seafood pasta.
You’re praising a specific choice.
Now imagine a different situation. A friend plans to drive several hours without checking the weather. You might say:
I strongly recommend checking the forecast first.
You’re emphasizing the action.
That distinction is useful because it shows how context shapes the adverb.
Product Review Example
I highly recommend these headphones. The sound is clear, the battery lasts all day, and they’re comfortable for long sessions.
The phrase introduces positive evaluation.
Advice Example
I strongly recommend reading the return policy before ordering.
Here, the recommendation focuses on something the reader should do.
Both are recommendations. The communicative purpose differs.
Strongly Recommend vs. Highly Recommend in Professional Endorsements
Professional recommendations deserve special attention because highly recommended can describe reputation.
For example:
She comes highly recommended by previous clients.
This doesn’t necessarily mean the current speaker personally knows her work. It can mean that other people have given her a strong reputation.
Cambridge specifically defines highly recommended in its Business English material as having an excellent reputation.
Compare these:
I highly recommend Sarah for the position.
Sarah comes highly recommended for the position.
The first directly expresses the speaker’s recommendation.
The second emphasizes the recommendation or reputation Sarah has received.
That difference can matter in professional writing.
Strongly Recommend vs. Highly Recommend: Common Sentence Patterns
Learning common patterns makes the distinction much easier.
| Pattern | Example |
| I strongly recommend + noun | I strongly recommend this guide. |
| I strongly recommend + -ing | I strongly recommend checking the settings. |
| I strongly recommend that + clause | I strongly recommend that you check them. |
| I highly recommend + noun | I highly recommend this book. |
| I highly recommend + -ing | I highly recommend visiting the museum. |
| I highly recommend that + clause | I highly recommend that you try it. |
| come highly recommended | The hotel comes highly recommended. |
These structures show that both adverbs can work with several grammatical patterns.
Strongly Recommend vs. Highly Recommended
Don’t confuse the active phrase with the adjective-like recommended construction.
Compare:
I strongly recommend this service.
The speaker actively makes the recommendation.
Now:
This service is highly recommended.
The second sentence uses a passive construction. It focuses on the service’s reputation or recommendation status.
The distinction becomes especially clear in:
She comes highly recommended.
That sentence can suggest that other people have spoken favorably about her.
Strongly Recommended
Strongly recommended can emphasize firm advice:
It is strongly recommended that visitors arrive early.
Highly Recommended
Highly recommended can emphasize excellent reputation:
This hotel is highly recommended by previous guests.
Both are correct. Their focus differs.
Strongly Recommend vs. Highly Recommend vs. “Strong Recommendation”
The noun phrase strong recommendation works differently.
Compare:
I strongly recommend this course.
Here, strongly modifies the verb recommend.
Now:
I have a strong recommendation for this course.
Here, strong modifies the noun recommendation.
You can also write:
My strong recommendation is that you review the material first.
The grammar changes, but the underlying idea remains similar.
Strongly Recommend vs. Highly Recommend vs. “Strongly Suggest”
Sometimes strongly suggest is a better alternative.
For example:
I strongly suggest checking the receipt before leaving.
This can sound more conversational than:
I strongly recommend checking the receipt before leaving.
The two expressions overlap, but suggest often feels slightly less formal or institutional.
Other alternatives include:
Alternatives for Strong Advice
- strongly suggest
- urge you to
- advise you to
- recommend that you
- encourage you to
Alternatives for Positive Approval
- highly endorse
- enthusiastically recommend
- confidently recommend
- heartily recommend
- give my full recommendation
Choose the alternative based on the tone you want rather than simply replacing words mechanically.
Common Mistakes With Strongly Recommend and Highly Recommend
Mistake: Assuming “Highly Recommend” Is Wrong
It isn’t.
I highly recommend this book is grammatical and widely used.
Dictionary examples from Cambridge include active uses of highly recommend, which confirms that the construction is standard English.
Mistake: Assuming “Strongly Recommend” Only Works for Warnings
It doesn’t.
You can say:
I strongly recommend this author.
You can also say:
I strongly recommend taking this course.
The phrase can express strong positive approval as well as firm advice.
Mistake: Treating One Phrase as Universally Better
There isn’t a universal rule saying that one phrase always wins.
Context matters.
I strongly recommend reviewing the contract.
sounds natural because the speaker emphasizes an important action.
I highly recommend this novel.
sounds natural because the speaker praises the novel.
But you can switch them in many contexts without creating a grammatical error.
Case Study: A Restaurant Recommendation
Imagine a friend asks about a restaurant.
Version A
I highly recommend the restaurant. The food was excellent, and the service was quick.
This sounds like a positive review.
Version B
I strongly recommend making a reservation before you go.
This sounds like practical advice.
Notice what changed.
The first sentence evaluates the restaurant.
The second emphasizes an action.
That’s the central distinction in miniature.
Case Study: Workplace Communication
Suppose an employee wants to send a project update.
Positive Endorsement
I highly recommend Maya for the project because of her experience with similar work.
The focus is Maya’s suitability.
Firm Advice
I strongly recommend reviewing the final figures before submitting the report.
The focus is the action that should happen next.
Both expressions work professionally. The intended message determines the better fit.
Case Study: A Product Review
Suppose you’ve tested a laptop for several weeks.
A natural review might say:
I highly recommend this laptop for students and remote workers.
You’re giving a positive assessment.
But suppose you’re explaining an important setup step:
I strongly recommend installing the latest security updates before using it.
Now you’re emphasizing a practical action.
The product hasn’t changed. The purpose of the sentence has.
Which Phrase Sounds Stronger?
There isn’t a universal scale where strongly recommend always ranks above highly recommend.
That’s an oversimplification.
Instead, think about what kind of strength you’re expressing.
Strongly can make the recommendation feel more forceful.
Highly can make the approval feel more elevated or enthusiastic.
For example:
I strongly recommend that you read the instructions.
The emphasis falls on the advice.
I highly recommend this guide.
The emphasis falls on the guide’s quality.
In some sentences, the difference becomes very small. That’s why native speakers can use the two expressions interchangeably without confusing the reader.
