Определение и Значение "subject"

What is the "subject"?

The subject is a key part of a sentence that indicates who or what the sentence is about. It typically performs the action of the verb or is described by the verb. For example, in the sentence "The cat sleeps," "The cat" is the subject that is performing the action of sleeping. The subject can be a single noun, such as "John," or a noun phrase, like "the tall building." In English, the subject usually appears before the verb in a sentence. Identifying the subject is important for understanding the main focus of the sentence and how the action or state of being relates to it.
