This document discusses the use of gerunds and infinitives when verbs are used nominally. Gerunds end in "-ing" and act as nouns, while infinitives use "to" before the verb. Some verbs are followed by gerunds or infinitives depending on their meaning, such as "try" followed by a gerund for experimenting and an infinitive for general purposes. Verbs like "start" refer to a long process with a gerund and something more general with an infinitive. Care must be taken with verbs like "remember" and "forget" which use gerunds for past actions and infinitives for present or future.
