How to say "Not" in Japanese

When translating "not" into Japanese, you must choose carefully between 間に合わない and まんざらでもない. In Japanese, 間に合わない (まにあわない (maniawanai)) is typically associated with "to not be in time, to miss (an appointment/train etc.)" (Syllabus Level: N4) and represents The negative form of 間に合う. On the other hand, まんざらでもない (まんざらでもない (manzara demo nai)) maps to "not bad, not entirely displeased, rather good (often with a hint of feigned indifference)" (Syllabus Level: N2) and represents A phrase used to express that something is actually quite good or pleasing, despite perhaps outwardly acting as if one is indifferent or critical. It conveys a subtle sense of satisfaction or quiet approval.. A literal translation of "not" can often sound unnatural to native Japanese speakers if mixed up!
