Gerunds
* Form: They are verbs that end in "-ing" and act as nouns.
* Function: They can be the subject, object, or object of a preposition in a sentence.
* Examples:
* Swimming is my favorite activity. (Subject)
* I enjoy reading. (Object)
* She's good at solving puzzles. (Object of the preposition "at")
Infinitives
* Form: They consist of the word "to" followed by the base form of a verb.

* Examples:
* To travel is my dream. (Noun)
* The best thing to do is to relax. (Adjective)
* She went to see a movie. (Adverb)
* I want to eat. (Part of a verb phrase)
Key Differences
* Function: While both can act as nouns, infinitives have a broader range of functions, including adjectives, adverbs, and parts of verb phrases.

Examples to Illustrate the Difference
