How to say "Not" in Japanese

When translating "not" into Japanese, you must choose carefully between あまり and まんざらでもない. In Japanese, あまり (あまり (amari)) is typically associated with "not much, not very (used with negative verb)" (Syllabus Level: N5) and represents Adverb. Always used with a negative form of a verb or adjective. 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!
