As...As: Comparing Equality and Inequality
The 'as...as' structure is the standard way to compare two things without using a comparative form. Between the two 'as' words, English always uses the base form of the adjective, never '-er' or 'more' — 'as fast as', never 'as faster as'. Negating the structure with 'not' reverses the meaning to inequality, and adding 'nearly' before a negative version signals a large rather than small gap.
Equality: as + base form + as
This second-hand bike is just as good as a new one.
Please come as soon as possible.
Inequality: not as + base form + as
Ana isn't nearly as rich as Susie. (a big difference, not a small one)
Multiples: twice/three times as...as
Common Mistakes
✗ Their house is twice bigger than ours. → ✓ Their house is twice as big as ours.
