What is a subject?


In a typical sentence, the two main components are the subject and the predicate.



The subject is the part of the sentence that typically indicates who or what the sentence is about.

The subject of a sentence can answer the questions who? and what?

It can be expressed using various forms, including nouns, pronouns, infinitives, gerunds, numerals, and other words or combinations that function as nouns.


Here are examples for each of these cases:
