as big as
The rule
When two things are equal, English puts the plain adjective between as and as: My flat is as big as yours. When they are not, the negative form says so: It is not as expensive as I thought. Nothing changes on the adjective — no -er and no more.
as + plain adjective + as · not as + plain adjective + as
Examples
My flat is as big as yours.
It is not as expensive as I thought.
The bus is not as fast as the train.
This one is just as good.
