Mnemonic
赤 aka — the noun "red"; the i-adjective 赤い lives on as a separate word. In Japanese, color runs in noun and adjective forms side by side through daily speech. 赤の他人 — a "red stranger," a complete stranger with not one drop of shared blood. Here 赤 carries the grain of "stark, sheer" — the same root in 赤裸々 and in 赤ちゃん. Kanji-reading kin: 赤 reads Korean 'jeok' (赤裸), Mandarin chì.
