Gerunds

A gerund is the -ing form of a verb used as a noun. It can be a subject, object, complement, or object of a preposition.

UseExample
SubjectSwimming is fun.
ObjectI enjoy reading.
ComplementMy hobby is painting.
After prepositionShe is good at cooking.

Smoking is harmful.

He avoids eating late.

Make it negative: I regret not studying.

Use a gerund (not an infinitive) after prepositions (good at cooking) and after verbs like enjoy, avoid, finish, mind.

Common mistake: Using an infinitive after a preposition: "good at to cook" → "good at cooking."
