The form by which we name a verb is called the root form. In Exercise 70 the root forms were given first. In that exercise you used the forms of the verbs drive, drop, have, and write.

Notice that the root form of a verb can be used as either a verb or a verbal. As a verb it expresses present time and may have I for a subject; for example, I drive, I have, I write. As a verbal, it is often preceded by the word to; for example, I like to drive, She wants to have a party, To write well requires practice. The word to preceding the root form used as a verbal may be considered as a part of the verbal. Thus we may say that the verbal drive or the verbal to drive is the object of the verb like in the sentence I like to drive.
