Comparative 3 (as...as / than)

Using as...as, not as...as, less than, the same as, and pronoun forms after than

not as … as

  • The town centre wasn’t as crowded as usual. (= it is usually more crowded)
  • I don’t know as many people as you do. (= you know more people)

You can also say not so … as with the same meaning:

  • It’s not warm, but it’s not so cold as yesterday.

less than = not as … as

Less than has a similar meaning to not as … as.

The city centre was less crowded than usual.It wasn’t as crowded as usual.

as … as in Positive Sentences and Questions

Use as … as (not so … as) in positive sentences and questions. The structure means “equally” or “to the same degree.”

  • I got here as fast as I could.
  • There’s plenty of food. You can have as much as you want.
  • Can you send me the information as soon as possible, please?
  • Let’s walk. It’s just as quick as taking the bus.

You can also say twice as … as, three times as … as, etc.

  • Their house is about three times as big as ours.

the same as

Use the same as (not the same like) to say two things are equal.

  • Laura’s salary is the same as mine.
  • David is the same age as James.
  • She still looks the same as she did ten years ago.

than me / than I am

After than or as, you can use me/him/her/us/them (object pronouns) or a clause with a subject + verb. Both forms are correct.

Object pronounFull clause
You’re taller than me.You’re taller than I am.
He’s not as clever as her.He’s not as clever as she is.
They have more money than us.They have more money than we have.
I can’t run as fast as him.I can’t run as fast as he can.

In everyday English, the object pronoun form (than me, as him) is more common. Avoid ending with a subject pronoun alone (than I, as she) — use a full clause instead (than I am, as she is).
