無敵

• 読み: むてき
• ローマ字: muteki
• 漢字の分解: 無 (without) + 敵 (enemy) → without enemies, invincible
• 発音: /mu.te.ki/

意味

Invincible — someone so dominant in their field or moment that nobody can touch them.

While 無敵 is a standard Japanese word meaning 'invincible,' its casual slang use amplifies this to describe someone in an unbeatable state: an athlete on a winning streak, a friend who is radiating confidence, or an idol who looks flawless. Often used with a sense of awe at someone's current unstoppable momentum.

例文

1. 今の彼女は無敵だよ、何やっても上手くいく。
