Three Gerund Rules

1. Subject = Gerund
When you need an action as a subject, use a gerund. Infinitives are possible, but they are very formal and not very common in this position.

Learning English has improved my confidence.

2. Preposition + Gerund
After a preposition, use a gerund. This is true for prepositions that are part of phrasal verbs, too.
I thought about calling my grandma, but I was too tired.
Are you planning on going to the party?

3. Verb + Gerund
A gerund or an infinitive can be used after a main verb. It depends on the verb, and there isn’t an easy rule for this case. Memorizing the most common verbs that take a gerund, such as advise, avoid, enjoy, finish, practice, quit, and suggest, is helpful.

*Don’t forget that some verbs take either a gerund or an infinitive with no change in meaning! Some common verbs include like, love, and hate.
