How ly adverbs are formed

Most ly adverbs are built by adding the suffix -ly directly to an adjective, so quick becomes quickly and careful becomes carefully. Some spelling changes apply along the way, such as easy becoming easily, but the basic pattern stays the same across most of the list. Recognizing this pattern makes it easier to turn a familiar adjective into an adverb on the spot.

Using ly words well in writing

Ly adverbs are useful for showing how, when, or how much something happens, as in she spoke quietly or he finished quickly. Writers are sometimes told to avoid them, but the real advice is to avoid weak ones that prop up a vague verb, not to cut every ly word on sight. Used with a strong verb, an ly adverb like suddenly or carefully can sharpen a sentence rather than weaken it.
