闇

• 読み: やみ
• ローマ字: yami
• 漢字の分解: 闇 (darkness/shadow) — originally literal darkness, slang usage emphasises moral darkness or hidden corruption
• 発音: /ja.mi/

意味

Dark, shady, or disturbing — used to describe something morally corrupt, sketchy, or deeply wrong.

Originally meaning literal darkness, 闇 exploded as slang in the 2010s through internet culture to describe anything with a sinister, shady, or morally questionable underbelly. It can describe corrupt organisations, illegal activities (闇バイト = shady side jobs), or the unsettling feeling that something has a dark side people don't see. The word carries a sense of ominous mystery and is often used when exposing or speculating about hidden wrongdoing.
