What are Gerunds and Infinitives?

Before we look at verb patterns, let’s quickly review what gerunds and infinitives are:

• A gerund is the -ing form of a verb that acts like a noun. For example, in I enjoy swimming, swimming is a gerund.
• ある infinitive is the base form of a verb, usually with to before it. For example, in I want to swim, to swim is an infinitive.

When two verbs are together, the first verb decides the form of the second verb.

Verbs Followed by Gerunds (-ing)

Many common verbs are always followed by a gerund (the -ing form of the verb). You cannot use to + infinitive after these verbs.

• 当社では avoid with a gerund: She avoids meeting new people.
• 当社では enjoy with a gerund: I enjoy watching movies.
• 当社では finish with a gerund: Have you finished studying?
• 当社では mind with a gerund (often in questions or negatives): Do you mind opening the window?
• 当社では suggest with a gerund: He suggested going for a walk.
• 当社では keep with a gerund: Keep practising, and you will improve.
• 当社では practise with a gerund: You should practise speaking English every day.

Remember that verbs after prepositions also always take the gerund form. For example:

• I'm good at playing tennis. (after at)
• She's thinking about moving to another city. (after about)
• I'm looking forward to seeing you. (after to, when to is a preposition)

Verbs Followed by Infinitives (to + verb)

Other common verbs are always followed by an infinitive (the to + base verb form). You cannot use the gerund after these verbs.

• 当社では decide with an infinitive: They decided to travel next month.
• 当社では expect with an infinitive: I expect to finish work early today.
• 当社では hope with an infinitive: She hopes to visit Paris soon.
• 当社では learn with an infinitive: He learned to play the guitar.
• 当社では need with an infinitive: We need to buy some food.
• 当社では offer with an infinitive: He offered to help me.
• 当社では plan with an infinitive: They plan to get married.
• 当社では promise with an infinitive: I promise to call you later.
• 当社では refuse with an infinitive: She refused to answer my question.
• 当社では want with an infinitive: I want to learn English.
• 当社では would like with an infinitive: I would like to drink some water.

Some verbs, like help, can be followed by an infinitive with to or without to. Both are correct: He helped me to carry the bags. または He helped me carry the bags.

例

• She avoids meeting other artists.
• The experience helped him to become a champion.
• Salma refused to give up.
• She learned to speak English quickly.
• Johnny Depp doesn't enjoy being famous.

• I could start saving money.
• He decided to leave to study acting.

練習

スペイン語話者がよく犯す間違い

Spanish speakers often make mistakes with gerunds and infinitives because the rules are different from Spanish. Here are some common errors:

• Using infinitive after prepositions: In Spanish, you use the infinitive after prepositions (e.g., antes de salir). In English, you must use the gerund.
  Incorrect: I'm interested in to learn English.
  Correct: I'm interested in learning English.
• Confusing verbs that take gerunds with those that take infinitives: It's easy to mix them up. For example, after enjoy, you must use a gerund.
  Incorrect: I enjoy to travel.
  Correct: I enjoy travelling.
• Using gerund where an infinitive is needed: For verbs like want, you must use an infinitive.
  Incorrect: I want buying a new car.
  Correct: I want to buy a new car.

The best way to avoid these mistakes is to memorize the common verbs in each category and practise using them.
