What is a subject?
The subject of a sentence is the person or thing about which an assertion is made or a question is asked . Subjects can either be "simple" (composed of a single pronoun, noun or noun phrase), "compound" or "complex" Examples: Fatima looked in the mirror. In this example, "Fatima" is the subject because the sentence asserts that she looked in the mirror. The scientist was correct in her prediction. In this example, "the scientist" is the subject because the sentence asserts that she made a correct prediction. Both of these sentences have simple subjects.
