不A不B
不A不B — neither … nor (just right)
Pattern
+ + +
A and B are opposite adjectives
( ) can be left out · other words may come before, between and after
How it works
不A不B puts 不 before each of two opposite words to mean "neither too A nor too B", i.e. just right (不大不小). It describes a comfortable middle between two extremes.
