真っ赤
まっか · makka · JLPT N3 · na-adj
flushed
🍅 真 true + 赤 red = true red; ma + aka squeezes into makka
The prefix 真 (ma) means pure or completely, as in 真っ白 masshiro (pure white) and 真っ黒 makkuro (jet black). The small っ doubles the next sound, so ma + aka becomes makka. It also covers flushed faces: 顔が真っ赤.
真 — 匕 (spoon) over 目 (eye) over 八 (eight/base)
真 originally depicted a person or vessel used in ritual, conveying the idea of something genuine or true. Over time the form was reanalyzed as components like 匕, 目, and a base, but the core meaning of 'real, true, genuine' has remained stable since early bronze inscriptions.
