本気

• 読み: まじ
• ローマ字: maji
• 漢字の分解: 本 (true/real) + 気 (spirit/feeling) → true feelings, dead seriousness. Standard reading is ほんき (honki), slang reading is マジ (maji)
• 発音: /ma.dʑi/

意味

Dead serious, for real — the kanji form of マジ, showing how traditional writing meets modern slang pronunciation.

While the standard reading of 本気 is ほんき (honki), in modern slang contexts it is frequently read as マジ (maji). This dual reading is especially visible in manga, where furigana shows マジ above 本気, creating a visual representation of traditional-meets-modern. The kanji adds weight and seriousness to the slangy マジ, as if saying 'I'm so serious I'm breaking out the kanji.' This interplay between formal writing and casual speech is quintessentially Japanese.
