A2 Elementary Comparison and adverbs of manner

as … as

Lesson goal. After this lesson you can say two things are the same or not the same using as … as.

When to use it

  • Saying two things are equal: Nam is as tall as Minh.
  • Saying one is less: This film isn't as good as the first one.
  • Rephrasing a comparative: smaller = not as big as.

Form

PatternExample
as + base adjective + asShe is as old as me.
not as + adjective + asHe is not as fast as you.
as + adverb + asHe runs as fast as me.
as much/many + noun + asI have as many books as you.

Step by step

  1. Identify the two things you compare.
  2. Put the adjective or adverb in its base form — no -er, no more.
  3. Sandwich it between the two as.
  4. For 'less than', add not before the first as.

Two ways to say the same thing

Comparativeas … as version
A is smaller than B.A isn't as big as B.
B is older than A.A isn't as old as B.
A and B are the same height.A is as tall as B.

Examples

Nam is as tall as his father.
This exercise isn't as difficult as I expected.
She speaks English as well as her teacher.
My phone isn't as expensive as yours.
I have as many friends as you do.
Today isn't as hot as yesterday.

Common mistakes

He is as taller as his brother. → He is as tall as his brother.
Between the two as you need the base adjective. The as … as frame already does the comparing.
She sings as good as him. → She sings as well as him.
Modifying the verb sings needs the adverb well.
This book is so interesting as that one. → This book is as interesting as that one.
Positive sentences use as … as. The so … as version is old-fashioned and only negative.

Memory tip

Picture the two as as hooks holding a sign. The sign between them must stay flat — the adjective keeps its base form.

Summary

  • Equal: as + base form + as.
  • Less: not as + base form + as.
  • Never put -er or more between the two as.
