From The Mother Tongue
by Bill Bryson

Consider the parts of speech. In Latin, the verb has up to 120 inflections. In English it never has more than five (e.g., see, sees, saw, seeing, seen) and often it gets by with just three (hit, hits, hitting). Instead of using loads of different verb forms, we use just a few forms but employ them in loads of ways. We need just five inflections to deal with the act of propelling a car — drive, drives, drove, driving, and driven — yet with these we can express quite complex and subtle variations of tense: “I drive to work every day,” “I have been driving since I was sixteen,” “I will have driven 20,000 miles by the end of this year.” This system, for all its ease of use, makes labeling difficult. According to any textbook, the present tense of the verb drive is drive. Every junior high school pupil knows that. Yet if we say, “I used to drive to work but now I don’t,” we are clearly using the present tense drive in a past tense sense. Equally if we say, “I will drive you to work tomorrow,” we are using it in a future sense. And if we say, “I would drive if could afford to,” we are using it in a conditional sense. In fact, almost the only form of sentence in which we cannot use the present tense form of drive is, yes, the present tense. When we need to indicate an action going on right now, we must use the participial form driving. We don’t say, “I drive the car now,” but rather ‘I’m  driving the car now.” Not to put too fine a point on it, the labels are largely meaningless. [Read more…]
