Infinitives in Spanish are the base form of verbs, equivalent to the English "to" + verb structure, such as "to eat" or "to run." They typically end in -ar, -er, or -ir. Infinitives can function as nouns in a sentence, act as the subject or object, and are often used after other conjugated verbs, prepositions, or expressions. Understanding how infinitives work is essential for constructing sentences, forming commands, and combining verbs in Spanish.
