Gerunds & Infinitives: Uses
Gerunds and infinitives can be used as:
-
the subject of the sentence
-
the object of the sentence
-
Subject of the sentence
-
Object of the sentence
Gerunds: Specific Uses
Both gerunds and infinitives can be the object of a sentence.
When the object follows a preposition, a gerund is generally used.
Gerunds are used after prepositions except the prepositions but and except.
For these two prepositions, we use an infinitive after.

Infinitives can also be used as:
-
Adjectives
The infinitive to use modifies the noun ingredients, acting as an adjective.
-
Adverbs
The infinitive to speak modifies the adjective nervous, acting as an adverb.

Choosing Between Gerunds and Infinitives
Follow these guidelines as a general rule when deciding to use a gerund or an infinitive:
-
Use a gerund when discussing something specific, real or that has already happened.
-
Use infinitives when discussing something abstract, not real or that only might happen.
Something specific, real or that has already happened
