Advise, Suggest and Recommend


The Core Difference

First, let's understand the nuance of each verb:

 * Advise: This is typically used for giving expert, formal, or strong guidance. It often implies that the speaker has more knowledge or authority.

   * Example: A doctor advises a patient. A lawyer advises a client.

 * Suggest: This is used to propose an idea, plan, or possibility for someone to consider. It's a more neutral and common term.

   * Example: A friend suggests a movie to watch.

 * Recommend: This is a strong suggestion based on personal positive experience or knowledge. You are endorsing something.

   * Example: You recommend a restaurant where you had a great meal.

Grammatical Structures for Reported Speech

Here are the main patterns you need to know.

1. Advise

The verb advise most commonly uses an object and an infinitive.

Structure 1: $advise + object + (not) + to-infinitive$

This is the most frequent and natural-sounding structure.

 * Direct Speech: "You should see a specialist," the doctor said to me.

 * Reported Speech: The doctor advised me to see a specialist.

 * Direct Speech: "I wouldn't buy that car if I were you," my father said.

 * Reported Speech: My father advised me not to buy that car.

Structure 2: $advise + that-clause$

This structure is more formal. The clause that follows often uses the subjunctive mood (the base form of the verb, e.g., be, take) or should.

 * Direct Speech: "It is important that the company invests in new technology."

 * Reported Speech: The consultant advised that the company (should) invest in new technology.

   (Note: Using 'should' is very common, especially in British English. The subjunctive 'invest' is more common in American English.)

Structure 3: $advise against + gerund (-ing form)$

This is used specifically for negative advice.

 * Direct Speech: "Don't travel alone at night."

 * Reported Speech: She advised against travelling alone at night.

2. Suggest

The verb suggest is the trickiest because it CANNOT be followed by an object + to-infinitive. This is the most common mistake learners make.

Incorrect: He suggested me to go home. ❌

Structure 1: $suggest + gerund (-ing form)$

This is used when the person suggesting is part of the group, or when the person being suggested to is obvious from the context.

 * Direct Speech: "Let's go for a walk," she said.

 * Reported Speech: She suggested going for a walk.

 * Direct Speech: "Why don't you try the new Italian restaurant?" he asked.

 * Reported Speech: He suggested trying the new Italian restaurant.

Structure 2: $suggest + that-clause$

This is used when you need to specify who should perform the action. Like with 'advise', it can be followed by the subjunctive mood or should.

 * Direct Speech: "You should take a holiday," my boss said to me.

 * Reported Speech: My boss suggested that I (should) take a holiday.

   (Notice we say "suggested that I take," not "suggested me to take.")

 * Direct Speech: "Peter should apply for the job," she said.

 * Reported Speech: She suggested that Peter (should) apply for the job.

Structure 3: $suggest + noun/pronoun$

You can also suggest a thing directly.

 * Direct Speech: "How about the blue one?"

 * Reported Speech: She suggested the blue one.

3. Recommend

The verb recommend follows the exact same patterns as suggest. It also CANNOT be followed by an object + to-infinitive.

Incorrect: The guide recommended us to visit the museum. ❌

Structure 1: $recommend + gerund (-ing form)$

 * Direct Speech: "You should definitely try visiting the old town."

 * Reported Speech: The guide recommended visiting the old town.

Structure 2: $recommend + that-clause$

 * Direct Speech: "I think you should read this book."

 * Reported Speech: He recommended that I (should) read that book.

Structure 3: $recommend + noun/pronoun (+ to + person)$

You can recommend a thing directly, and you can specify who it is recommended to.

 * Direct Speech: "The fish is excellent here."

 * Reported Speech: The waiter recommended the fish.

 * Direct Speech: "You should watch 'The Crown'," she said to me.

 * Reported Speech: She recommended 'The Crown' to me.

Final Recommendations for You:

 * Memorize the Golden Rule: Never use $suggest + object + to-infinitive$ or $recommend + object + to-infinitive$. This is the single most important rule to remember.

 * Use Gerunds for Simplicity: When the subject is clear, using the gerund (-ing) form after suggest and recommend is often the easiest and most natural choice. (e.g., "He suggested leaving.")

 * Use advise with a Person: Remember that advise almost always needs an object (a person or group) before the action. You advise someone.

 * Practice: Try converting direct speech sentences into reported speech using these three verbs. For example, turn these sentences into reported speech:

   * "You should take a taxi," my friend said. (Use advise)

   * "Let's order a pizza," said Tom. (Use suggest)

   * "The historical museum is worth visiting," the tour guide said. (Use recommend)

In Other Words

* When advise is followed by a
(pro)noun object, an infinitive is used.
 * When there is no (pro)noun object
after advise, a gerund is used.
* Suggest and recommend can also be
followed immediately by a gerund.
Suggest and recommend cannot be
followed by a (pronoun object and an
infinitive, but they can be followed by a
'that-clause" in which should is used.

*The use of should in the noun clause is not necessary. However, if should is not used, the verb in the noun clause is always in the simple form after suggest and recommend:

Ed suggested/recommended that{

I call a doctor. (not called)
We call a doctor. (not called)

Ann call a doctor. (not calls or called)
He call a doctor. (not calls or called)
