Comparatives for equality
A1 BeginnerUse 'as + adjective + as' to say two things are the same, and 'not as + adjective + as' to show they are different.
Overview
We use this structure to compare two people, places, or things. When we use as... as, we mean the two things are equal in some way. When we use not as... as, we mean the first thing has less of a quality than the second thing.
Form
(not) as + adjective + as
Place the base form of the adjective between the two words. Do not use the comparative form (like 'taller' or 'more expensive') here.
Examples
Common mistakes
He is as taller as me.
He is as tall as me.
Use the base adjective, not the -er form.

Always use 'as' for the second part of the comparison, not 'than'.
