正直
しょうじき · shoujiki · JLPT N3 · na-adj
honesty
正直 = correct (正) + straight (直): correct and straight = honest
正 means correct or upright, 直 means straight or direct. Someone who is both correct and straight with you is honest. Sound hook: shoujiki starts like show — an honest person will show you the truth, no tricks.
正 — one 一 + stop 止
Originally an ideograph showing a foot (止) advancing toward a target line (一), meaning 'to march straight toward' a city or goal. From this came the senses 'upright,' 'correct,' and 'proper.' The military sense survives in 征 (to campaign), which took over the original 'march' meaning.
直 — 十 ten + 目 eye + 乚 hidden line
Originally depicted an eye (目) looking straight along a vertical line, suggesting a direct, unswerving gaze. The form combines 目 'eye' with strokes indicating straightness. From this came the meanings 'straight,' 'upright,' and by extension 'honest' or 'direct.'
