Comparative:

• The opposite of more is less:

Milly's less moody than Debbie.

• When we compare two things in the same sentence we use than after the comparative:

Debbie's more selfish than Milly.

• We use a lot or much before the comparative to say there's a big difference:

She's a lot tidier. Milly's much more considerate than Debbie.

• We use a bit before the comparative to say there's a small difference:

She's a bit more mature.

TIP • We can also use more with nouns:

He's got more money than her. I've got more free time than my brother.

(NOT) AS +ADJECTIVE +AS

• We can also use not as + adjective + as to compare two people or things that are different:

Debbie isn't as happy as Milly. (=Milly is happier than Debbie).

• We use as + adjective + as to say that two people or things are the same:

Milly's as confident as Debbie. (= they are both equally confident).

• We use the adjective with (not) as ... as, not the comparative form:

She isn't as happy as her sister. ~~She isn't as happier as her sister.~~

• We don't use than with (not) as ... as:

She's as confident as her sister. ~~She's as confident than her sister.~~

Superlative:

The opposite of most is least:

He's my least favourite relative.

TIP• Before superlatives in sentences we use the

She's the happiest person I know.

possessive's

He's Jake's best friend.

or a possessive adjective

She's our richest relative.

the + superlative is the most common form.
