How to say "Not" in Japanese

When translating "not" into Japanese, you must choose carefully between あまり and いっさい. 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, いっさい (いっさい (issai)) maps to "(not) at all, absolutely (not), entirely (without)" (Syllabus Level: N2) and represents Used with negative verbs to emphasize a complete lack or absence of something. Stronger than 全然. A literal translation of "not" can often sound unnatural to native Japanese speakers if mixed up!
