2. DEFINITIONS
Adjectives are words that describe nouns or
pronouns. They may come before the word they
describe (That is a cute puppy.) or they may follow the
word they describe (That puppy is cute.).
Adverbs are words that modify everything but nouns
and pronouns. They modify adjectives, verbs, and
other adverbs. A word is an adverb if it answers how,
when, or where.
3. EXAMPLES:
She thinks slow/slowly. Slowly answers how she
thinks.
We performed bad/badly. Badly answers how we
performed.
She thinks fast/fastly. Fast may be either an adjective
or an adverb. In this example, fast answers how she
thinks. There is no such word as fastly.
When comparing, don’t drop the -ly. Simply add more
or less.
Example:
He speaks more slowly than his brother.
4. EXAMPLES:
Rule: English grammar has one tricky caveat that seems like an
exception to these easy rules: If the verb is one of these four
senses—taste, smell, look, feel—don’t ask how. Instead, ask if the
sense verb is used actively. If so, attach the -ly. If the sense verb is
not used actively, which is more common, don’t attach -ly.
Examples:
Roses smell sweet/sweetly. Do roses actively smell with noses? No,
so no -ly.
The woman looked angry/angrily. Is the woman actively looking with
eyes? No, only her appearance is being described.
She feels bad/badly about the news. She is not feeling with fingers
so no -ly.
She feels bad/badly since burning her fingers. She feels with her
fingers here so the adverb (-ly form) is used.
