An indefinite verb, also known as an infinitive verb, is a verb form that is not conjugated to show any specific tense, mood, or subject. It is often used as the base form of the verb, without any additional endings. Synonyms for indefinite verb include "to-infinitive", "base verb" or "uninflected verb". The term "to-infinitive" refers to the form of a verb that begins with the word "to", like "to go" or "to eat". The phrase "base verb" emphasizes the unaltered form of the verb, while "uninflected verb" highlights that no conjugations are added to the verb form. These synonyms are commonly used in grammar and linguistic contexts to describe the non-inflected form of a verb.
