This document discusses the differences between gerunds, infinitives, and base forms of verbs in English. Gerunds are verbs with "-ing" added and can be used as subjects or objects. Infinitives always include "to" and can be subjects or objects after certain verbs and adjectives. Base forms are used after perception verbs and "let" or "make." Certain verbs like "stop," "remember," "regret," and "forget" can be followed by either a gerund or infinitive with subtle differences in meaning.
