次元が違う

• 読み: じげんがちがう
• ローマ字: jigen ga chigau
• 漢字の分解: 次 (next) + 元 (origin) + が (subject marker) + 違 (differ) + う (verb ending)
• 発音: /dʑi.ɡeɴ ɡa tɕi.ɡa.ɯ/

意味

On a completely different level — someone or something operating in a league so far above that comparison is pointless.

While 異次元 can carry sarcasm, 次元が違う is almost exclusively used as genuine praise or awestruck acknowledgment. It expresses that the gap between the subject and everything else is not just large but dimensional — as if they exist in a different reality. Common in sports, music, and any field where someone's skill is overwhelmingly superior. The phrase can also be used self-deprecatingly to acknowledge one's own inferiority when confronted with extraordinary talent.

例文

1. プロの技術見たら次元が違うって痛感した。
2. あの人の英語力、次元が違うから比べるのやめよ。
3. 生で聴いたら音源と次元が違う迫力だった。
