Infinitives and gerunds

Infinitive is the " very that follows ' to ' " .

eg : I want to get something to eat. ' to get ' is infinitive

Gerund is ' verb + ing ' to turn the verb into a noun.

eg : I like swimming. ' Swim ' is a verb, but after adding ' ing ' to it. It has become a gerund and also a noun.

The main different between a noun and gerund is gerund involves kind of action because it derives from a ' verb ' .
