The infinitive is a non-finite verb form that functions as a noun, adjective, or adverb in a sentence. It is typically marked by the base form of the verb, preceded by the word "to" (e.g. "to run," "to eat," "to study").

Some nominal features of the infinitive include its ability to serve as the subject or object of a sentence (e.g. "To swim is my favorite hobby" or "I want to eat dinner"), its ability to be modified by adverbs or adjectives (e.g. "to quickly finish" or "to deliciously eat"), and its ability to be the complement of certain verbs or prepositions (e.g. "I forgot to call" or "She is eager to learn").

Overall, the infinitive's nominal features allow it to function as a versatile and essential element in English grammar.
