Discover the difference between SUGGEST and RECOMMEND, their correct grammatical structures, and the most common mistakes.

If you have ever wondered what the difference between suggest and recommend is, or why you can’t say «I suggest you to go», you have come to the right place. These two verbs are incredibly useful in English, but they are also responsible for some of the most common errors among students of all levels.
Although both verbs are translated similarly into Spanish (sugerir and recomendar), their grammatical structures have specific characteristics that can be confusing. In this article, we are going to break down everything you need to know about suggest and recommend, including their differences, correct structures, typical errors, and how they appear in Cambridge exams.
Although suggest and recommend are quite similar, there is a subtle but important difference between them:
Let’s look at a practical example:
That being said, in many contexts both verbs are interchangeable, and the difference is so subtle that native speakers often use them interchangeably. What is really important is to master their grammatical structures, which is where problems usually arise.
The verb suggest can appear in several different structures. Let’s look at all of them with clear examples so you can master them completely.
This is the simplest structure. You simply place a noun after the verb:
Notice that you can optionally add «to me», «to us», etc., but it is not obligatory.
When you want to suggest an action, you use the gerund (the -ing form of the verb):
This structure is very common and relatively easy to remember. If you are just starting out, I recommend you focus on mastering this form first.
This is where things get a bit more complicated. When you use suggest followed by that and a person, the verb that follows must be in the subjunctive. In English, the present subjunctive has the same form as the infinitive without to:
Look at the third example: we say «he take», not «he takes». This is because we are using the subjunctive, not the present simple.
You can also use the past subjunctive or add should:
Later in this article, we will go deeper into the topic of the subjunctive with these verbs.
The most typical mistake English students make is using the infinitive with to directly after suggest:
This structure does NOT exist in English. Never use suggest + person + infinitive. It is probably the most common error with this verb, and it happens because in Spanish we do say «te sugiero ir» or «le sugerí que fuera».
The correct forms would be:
The verb recommend works very similarly to suggest, but with one important difference: it does allow the use of the infinitive with to in certain cases. Let’s look at all its structures.
Just like with suggest, you can use a noun directly:
You can also use the gerund to recommend an action:
Just like suggest, recommend can be followed by that and the subjunctive:
And here is the big difference with suggest: recommend can be followed by an object and an infinitive with to:
This structure is perfectly correct with recommend, but remember: it does NOT work with suggest.
Although recommend is more flexible than suggest, there are still errors you should avoid:
So you can see all the structures at a glance, here is a complete comparative table:
| Structure | Suggest | Recommend |
|---|---|---|
| + noun | ✅ He suggested a film. | ✅ He recommended a film. |
| + gerund (-ing) | ✅ He suggested watching a film. | ✅ He recommended watching a film. |
| + that + subjunctive | ✅ He suggested (that) we watch a film. | ✅ He recommended (that) we watch a film. |
| + that + should | ✅ He suggested (that) we should watch a film. | ✅ He recommended (that) we should watch a film. |
| + object + infinitive | ❌ He suggested us to watch a film. | ✅ He recommended us to watch a film. |
As you can see, the only important structural difference is that recommend allows the construction with object + infinitive, while suggest does not.
Both suggest and recommend belong to a group of verbs known as verbs of urgency or mandative verbs. These verbs express suggestions, recommendations, orders, or requests, and they have an important grammatical peculiarity: they are followed by the subjunctive.
The subjunctive in English may seem strange at first, especially because in the present tense it has exactly the same form as the infinitive without to:
This topic is part of advanced English grammar and is especially relevant when studying reporting verbs and reported speech in English.
Originally, these structures included should:
Over time, English simplified this structure and should became optional, leaving only the verb in its base form (the subjunctive):
Both forms are correct nowadays, although the version without should is more common in American English, while the version with should is more frequent in British English. If it is easier for you, you can always use the form with should and you will be perfectly correct.
In addition to suggest and recommend, there are other verbs that work the same way:
There are also impersonal expressions that follow the same rule:
If you are preparing for a Cambridge exam, it is fundamental that you master these verbs, as they frequently appear in both the B2 First Use of English and the C1 Advanced Use of English.
In the Use of English, it is common to find sentence transformation exercises where you have to change from one structure to another:
B2 First (FCE) style example:
«Why don’t we go to the cinema?» he said.
SUGGESTED
He ____________________ to the cinema.
Answer: suggested going / suggested that we go / suggested that we should go
C1 Advanced (CAE) style example:
The doctor told me it would be a good idea to reduce carbs intake.
CUT
The doctor recommended ____________________ on carbs.
Answer: that I cut down / that I should cut down / me to cut down
In the Writing, using suggest and recommend correctly can make a difference to your score, especially in:
💡 Examiner tip: At B2 and C1 levels, examiners value the correct use of complex structures positively. Using suggest/recommend + that + subjunctive demonstrates an advanced level of grammar. However, if you are not sure, it is better to use the simpler structure with a gerund than to risk making a mistake.
Although suggest and recommend are very useful, sometimes it can be convenient to use other similar verbs, especially to avoid repetition in your writing or to fit the context better.
Advise is more formal than suggest and recommend, and it is used especially when the advice is based on specialised knowledge or professional authority. It is common in legal, medical, or security contexts.
Structures with advise:
The advantage of advise is that its structure is simpler and very common. If you have doubts with suggest or recommend, advise can be a good alternative.
Propose is mainly used in formal contexts, such as business meetings or discussions where agreements or consensus are sought.
Structures with propose:
Propose works very similarly to suggest, but it has a more formal tone and is more associated with concrete plans or ideas than with simple suggestions.
Finally, you can always opt for simplicity and use should:
Using should is perfectly correct and, in fact, much more common in everyday spoken English. The difference is that should is more direct (almost a gentle order), while suggest and recommend are more diplomatic and present the idea as an option.

After everything we have seen, here are some practical tips that will help you use suggest and recommend correctly and without hesitation:
If you are at an intermediate level, focus on mastering suggest/recommend + gerund. It is the safest structure and works in most situations:
Once you master this structure, you can start exploring the others.
This is the most common mistake and the easiest to avoid if you are clear about it:
With recommend you can use this structure, but with suggest, never.
If you are not sure which structure to use, advise can save you:
It is more formal, but it is correct and easy to use.
If the subjunctive is complicated for you, start by using should in your that structures:
It is perfectly correct and gives you more confidence until you feel comfortable with the subjunctive.
The best way to internalise these structures is to see them in context. Pay attention to how native speakers use suggest and recommend in films, series, podcasts, or articles. You will see that in everyday spoken English, they often opt for simpler structures or directly use should.
These verbs are complicated even for advanced students. The important thing is that you communicate and that you gradually refine your usage. Every time you are corrected or you notice a mistake, you will be one step closer to mastering them completely.
As we have seen, although suggest and recommend have very similar meanings, their grammatical structures present some important differences that you should know. The key is remembering that suggest is never followed by person + infinitive, while recommend does allow this construction.
If you are just starting out, focus on mastering the gerund structure (suggest/recommend + -ing), which is the safest and most natural. As you progress, you can incorporate the structures with the subjunctive, which are especially useful in formal contexts and in Cambridge exams.
