A noun functions as the subject of a sentence or a clause, and as the object of a verb or a preposition.

A verb tells what the subject is or what the subject does.

Examples:

The drive to the city was tiring. (subject of the sentence)

He said that Maple Drive was the first right. (subject of the relative clause)

We can drive to the beach later today. (verb)

These insurance forms are going to drive me crazy. (verb)

She has the drive to succeed. (direct object of the verb 'has')

Would you like to go for a drive? (object of the preposition 'for')
