Infinitives in English Grammar

This video tutorial covers the concept of infinitives, a type of non-finite verb. It explains how infinitives are formed by adding 'to' before the base form of a verb and their roles as nouns, adjectives, and adverbs in sentences. The video also introduces bare infinitives, which function without the 'to' marker. Examples are provided for each usage type, and the lesson concludes with a recap of key points.
