Infinitives are uninflected verbs paired with the word "to," as in "to run," "to boost," or "to go." Infinitives can function as a noun, an adjective, or an adverb. It is important to note that, although they are formed from verbs, infinitives cannot be pluralized like its non-infinitive verb can (adding s or es). Students will use the following activity sheets to learn how to recognize, construct, and use infinitives. Answer sheets have been provided.
Fun Fact: The "rule" about not splitting infinitives grew out of a desire to make English more like Latin, but English is more flexible, so it can be done within reason.
