Mnemonic
赤い akai — i-adjective. Inflection: 赤い (predicative) / 赤く (adverbial, before naru/suru/te → 赤くなる "to turn red") / 赤かった (past) / 赤くない (negative). A separate noun form 赤 (aka) exists — like English splitting "red (noun)" vs "red (adj)" or Korean ppalganda vs ppalgang. High-frequency collocation: 顔が赤い = "face is red" (blushing, drunk, post-exercise). Textbook example of i-adjective inflection.
