同じ
おなじ · onaji · JLPT N5 · na-adj
same
👯 Oh nah, G — we showed up in the same outfit
onaji sounds like oh-nah-G, the groan you make when someone has the identical thing you do. The kanji 同 also appears in Chinese 同 (tóng) with the same meaning, so 同じ = 同 (same) + じ, an old adjectival ending.
同 — 冂 enclosure + 一 + 口 mouth
Originally depicted multiple mouths gathered under one cover or enclosure, suggesting people speaking together in agreement. From this image of voices joining, it came to mean 'same,' 'together,' or 'alike.' The shared cover symbolizes unity.
