What Is an Adverb?

Adverbs are helpful when we want to provide a little more information to a sentence. And, although they love to work with verbs, they can also team up with adjectives and other adverbs. A great way to spot adverbs is to look for words that end in -ly. Examples from the above list include "independently" and "intuitively."

We can get a little more specific than simply saying adverbs add intensity or emphasis to other words. Let's take a closer look at what, intrinsically, they aim to do:

  • Adverbs Tell How It Happened: Adverbs like "incredibly" describe how something was done.
  • Adverbs Tell Where It Happened: Adverbs like "inside" describe the location of where something happened.
  • Adverbs Tell When It Happened: Adverbs like "instantly" describe when something took place.
  • Adverbs Tell the Extent of an Action: Adverbs like "intermittently" describe the extent to which something did or did not happen.

Intermittent Additions

Adverbs make wonderful - though intermittent - additions to our writing. We should use them, but with caution. If we pair up our verbs with too many -ly words, things will soon become clunky.

Adding adverbs intermittently to our writing, however, will make interesting additions to your writing. And, while you're exploring I-adverbs, why not dabble in some I-adjectives? As your adverbs dress up your nouns, so, too, can your adjectives dress up your nouns.
