Definition - 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.).
Definition - 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.
The only adverbs that cause
grammatical problems are those that answer the question how, so
focus on these.
|
|
Examples:
|
He speaks slowly.
Answers the question how.
|
He speaks very slowly.
Answers the question how
slowly.
|
|
Rule 1.
|
Generally, if a word answers the
question how, it is an adverb. If it can have an -ly added to
it, place it there.
|
|
Examples:
|
She thinks slow/slowly.
She thinks how? slowly.
|
She is a slow/slowly
thinker.
Slow does not answer how, so no -ly is attached. Slow
is an adjective here.
|
She thinks fast/fastly.
Fast answers the question how, so it is an adverb. But fast
never has an -ly attached to it.
|
We performed bad/badly.
Badly describes how we
performed.
|
|
Rule 2.
|
A special -ly rule
applies when four of the senses - taste, smell, look, feel
- are the verbs. Do not ask if these senses answer the question how
to determine if -ly should be attached. Instead, ask if the sense
verb is being used actively. If so, use the -ly.
|
|
Examples:
|
Roses smell sweet/sweetly.
Do the roses actively smell with noses? No, so no -ly.
|
The woman looked angry/angrily.
Did the woman actively look with eyes or are we describing her appearance?
We are only describing appearance, so no -ly.
|
The woman looked angry/angrily
at the paint splotches.
Here the woman did actively look with eyes, so the -ly is added.
|
She feels bad/badly about
the news.
She is not feeling with fingers,
so no -ly.
|
|
Good vs. Well
Rule 3.
|
The word good is an
adjective, while well is an adverb.
|
|
Examples:
|
You did a good job.
Good describes the job.
|
You did the job well.
Well answers how.
|
You smell good today.
Describes your odor, not how you smell with your nose, so follow with the
adjective.
|
You smell well for someone with
a cold.
You are actively smelling with a
nose here, so follow with the adverb.
|
|
Rule 4.
|
When referring to health, use well
rather than good.
|
|
Examples:
|
I do not feel well.
|
You do not look well today.
|
|
NOTE:
|
You may use good with feel
when you are not referring to health.
|
|
Example:
|
I feel good about my decision to
learn Spanish.
|
|
Rule 5.
|
A common error in using
adjectives and adverbs arises from using the wrong form for comparison. For
instance, to describe one thing we would say poor, as in, "She
is poor." To compare two things, we should say poorer,
as in, "She is the poorer of the two women." To compare
more than two things, we should say poorest, as in, "She is the
poorest of them all."
|
|
Examples:
|
One
|
Two
|
Three or More
|
|
|
sweet
|
sweeter
|
sweetest
|
|
|
bad
|
worse
|
worst
|
|
|
efficient*
|
more efficient*
|
most efficient*
|
*Usually with words of three or
more syllables, don't add -er or -est. Use more or most
in front of the words.
|
|
Rule 6.
|
Never drop the -ly from
an adverb when using the comparison form.
|
|
Correct:
|
She spoke quickly.
|
She spoke more quickly than he did.
|
Incorrect:
|
She spoke quicker than he did.
|
Correct:
|
Talk quietly.
|
Talk more quietly.
|
Incorrect:
|
Talk quieter.
|
|
Rule 7.
|
When this, that, these,
and those are followed by nouns, they are adjectives. When they
appear without a noun following them, they are pronouns.
|
|
Examples:
|
This house is for sale.
This is an adjective here.
|
This is for sale.
This is a pronoun here.
|
|
Rule 8.
|
This and that are singular, whether they are being
used as adjectives or as pronouns. This points to something nearby
while that points to something "over there."
|
|
Examples:
|
This dog is mine.
|
That dog is hers.
|
This is mine.
|
That is hers.
|
|
Rule 9.
|
These and those are plural, whether they are being used
as adjectives or as pronouns. These points to something nearby while
those points to something "over there."
|
|
Examples:
|
These babies have been smiling
for a long time.
|
|
These are mine.
|
Those babies have been crying
for hours.
|
Those are yours.
|
|
Rule 10.
|
Use than to show
comparison. Use then to answer the question when.
|
|
Examples:
|
I would rather go skiing than
rock climbing.
|
First we went skiing; then we
went rock climbing.
|
