An infinitive is the root form of a verb combined with “to (e.g., to read, to write). While it does not convey tense, it brings the idea of an action or state in its purest form. Importantly, the infinitive form does not serve as a main verb in a clause but complements other elements or serves in another grammatical capacity.

Split Infinitives

A split infinitive is an adverb between the words to and the verb (e.g., to boldly go.) Split infinitives are grammatically correct, although they are avoided in formal writing, and using them can provide emphasis or flow.

Bare Infinitives

Bare infinitives are infinitives without the to (e.g., “help her finish rather than to finish). They are used after certain verbs like let, make, see, and hear. For example:

  • “They made her sing.”
  • “I saw him leave early.”
