"Simple subject" is the term used for the single word that is the subject of a verb.

A simple subject will often have modifiers before or after it, but, once these are removed, the word left is the simple subject.

Why Simple Subjects Are Important

Here are three good reasons to think more carefully of the simple subject.

(Reason 1) The simple subject nearly always determines the number of the verb.

The simple subject nearly always determines the number of the verb (i.e., whether it is singular or plural).

Be aware that the modifiers around a singular simple subject can sometimes fool a writer into using a plural verb. For example: This is covered more in the lessons on prepositional phrases, subjects, and subject-verb agreement.

(Reason 2) The simple subject does not always determine the number of the verb.

A noun phrase is a phrase that plays the role of a noun. The head word in a noun phrase will be a noun or a pronoun. The head word is the simple subject. In the examples below, the noun phrases are shaded and the simple subjects are in bold.

The overwhelming majority of the time, the simple subject will determine the number of the verb (i.e., whether it is singular or plural). However, this is not always the case. On rare occasions, the sense of a noun phrase can determine number. For example:

(Reason 3) Terms Like "half of" and "the majority of" can be singular or plural.

half singular or plural?

In expressions such as "a half of," "a part of," "a percentage of," "a proportion of," and "a majority of," the word before "of" is the simple subject. Even though these words look singular, they are only treated as singular when they refer to something singular. They are treated as plural when they refer to something plural. For example:

This point is the opposite of the point made in "Reason 1" above. With terms like "a half of," "a part of," etc., the modifier does affect the number of the verb. Read more about subject-verb agreement.
