What it is

This lesson is about words and phrases that describe or compare. A modifier describes another word. An adjective describes a noun (a careful clerk); an adverb describes a verb, an adjective or another adverb (works carefully, very tired).

You will learn to keep items in a list in the same form (parallel structure) and to place modifiers next to the words they describe. You will also learn the degrees of comparison (tall, taller, tallest), the order of adjectives, and how to choose the right adverb.

Why it matters on the exam

Error-identification and sentence-correction items often test these points: to sort, filing and copy; Walking to work, the rain started; more safer; the best of the two; most unique; sings good; everyday for every day. Many of these sound normal in casual speech, so you need the rule to catch them.

At work, clear modifiers and correct comparisons keep reports accurate: a misplaced phrase can make a sentence say the wrong thing.
