誠実
せいじつ · seijitsu · JLPT N1 · na-adj
honest
🤝 誠 = word (言) + become (成); 実 = real/true: a word that becomes true = sincere
誠 combines 言 (speech) and 成 (fulfil), so it means speech that is carried out. 実 means real or true (it also means fruit). Together they describe someone whose words match their deeds.
