Another expression that uses the 名詞（めいし） (noun) ほど ‘an extent’ in Japanese, is ほど～ない
. In the (A) part of a sentence, an extent will be highlighted, before the (B) part of the sentence will use ない to negate that extent, saying that it has not been reached. This phrase can be translated as ‘it isn’t like (A)’, ‘it’s not to the point of (A)’. Literally it means ‘if (A) is the extent, then (B) is not true’.
ほど will regularly be used after a verb or noun, while ない is more likely to be used after a verb, い-Adjective
, or な-Adjective
(as it is describing something about ほど).
Today wasn't as hot as I expected.
It is nothing to worry about so much. (This is not as serious as you think it is)
Bicycles aren't as fast as cars, but it is good for my health, so I ride my bike to work.
There is no food as spicy as this curry in the world.
While this grammar point may be used for expressing that an extent has not been reached, it is also frequently used for making comparisons between two things. In these cases, it states that ‘the example/limit of (A) is something that cannot be reached/repeated by (B)’. This is similar to ‘(B) is not as ~ as (A)’ in English.
