To Teach vs Teaching Infinitives & Gerunds

📝

Notes from a Native English Speaker

Infinitives: An infinitive is the base form of a verb, usually preceded by the word "to" (e.g., to swim, to eat, to learn). It can function as a noun, adjective, or adverb in a sentence. Infinitives are often used to express intentions, purposes, desires, or potential actions. Gerunds: A gerund is the -ing form of a verb (e.g., swimming, eating, learning). It’s different from a “present participle” which functions as a verb tense. A gerund can be the subject, object, or complement of a sentence.
