We use comparative adverbs when talking about two actions (not three or more actions). Comparison is always between TWO things.

How do we Make Comparative Adverbs?

There are three basic ways to make or "form" a comparative adverb:

1. One-syllable adverbs: add -er

If an adverb has only one syllable, we usually just add -er to make it comparative: fast → faster. Here are some examples:

adverb comparative adverb

fast faster

hard harder

high higher

late later

long longer

low lower

wide wider

Note that most one-syllable adverbs have the same form as their equivalent adjectives. Don't let this confuse you. For example:

positive comparative

adjective a fast car a faster car

adverb he drives fast he drives faster

2. Two-syllable adverbs: use more

When an adverb has two or more syllables (like all -ly adverbs), we can make it comparative by adding more in front: quickly → more quickly. Look at these examples:

adverb comparative adverb

carefully more carefully

efficiently more efficiently

happily more happily

horribly more horribly

often more often

quickly more quickly

recently more recently

slowly more slowly

sadly more sadly

strangely more strangely

We can also use less in place of more to suggest a reduction in the action. Look at these examples:

sentence for example

She visits often. once a week

Now she visits more often. ↑ once a day

Now she visits less often. ↓ once a month

3. Irregular Adverbs

A few adverbs have irregular form, for example:

adverb comparative adverb

badly worse

early earlier

far further/farther

little less

much more

well better

Comparative Adverbs with Informal Forms

Note that a few adverbs have a formal ("correct") form with -ly and an informal form without -ly. The same is then true of their comparative forms. Although you may hear some native speakers using the informal form in speech, it is best avoided in formal situations and examinations. The most common examples are:

adverb comparative adverb

cheap/cheaply cheaper/more cheaply

loud/loudly louder/more loudly

quick/quickly quicker/more quickly

slow/slowly slower/more slowly

Note that a few adverbs have NO comparative form, for example:

again, first

daily, yesterday

here, there

now, then

never, sometimes

How do we Use Comparative Adverbs?

Now that you know how to make comparative adverbs, let's see how to use them. Look at these examples. Notice that we may use more to suggest an increase in the action and less to suggest a decrease in the action. Notice also that the comparative adverb is often followed by than:

Trains go fast but planes go faster.

Planes go faster than trains.

Trains don't go faster than planes.

Trains go more slowly than planes.

Planes go less slowly than trains.

Joe won because he played better than Jane played.

Joe won because he played better than Jane.

Joe won because he played better.

Did cities grow more quickly after the Industrial Revolution?

He hit the ball more powerfully than his competitor.

As we get older we remember things less easily.

Could you talk a bit more quietly please?

Could you talk a bit less loudly please?

I can't hear you. Please speak louder/more loudly.
