語彙力

• Reading: ごいりょく
• Romaji: goiryoku
• Kanji breakdown: 語 (word) + 彙 (collection) + 力 (power)
• Pronunciation: /ɡo.i.ɾʲo.kɯ/

Meaning

Vocabulary power — used self-deprecatingly when you are so moved, impressed, or overwhelmed that words completely fail you.

語彙力 literally means 'vocabulary ability' and in its slang usage almost always appears in the negative — 語彙力がない (no vocabulary power), 語彙力を失う (lost my vocabulary power), or simply 語彙力… trailing off into speechlessness. It's a distinctly Japanese way of expressing being awestruck: rather than trying to find superlatives, you announce that your language faculty has shut down. The beauty of a sunset, an idol's performance, an incredibly delicious meal — all can rob you of your 語彙力. It's simultaneously self-deprecating and a massive compliment to whatever left you speechless.

Examples

1. 推しの新ビジュアル見た瞬間語彙力失った。 The moment I saw my idol's new look I lost all vocabulary power.
2. この景色すごすぎて語彙力ない、とにかくやばい。 This view is so incredible I have no vocabulary — all I can say is 'wow.
3. 美味しすぎて語彙力が追いつかない、もう「美味しい」しか言えない。 It's so delicious my vocabulary can't keep up — all I can say is 'delicious.

Usage Guide

Context: fan culture, social media, reactions to beauty or food

Tone: awestruck, self-deprecating, humorous

Do Say

• 語彙力なくて申し訳ないけどほんとにすごい。 (Sorry for having no vocabulary but it's truly amazing.)
• 語彙力が死んだ、何も言えない。 (My vocabulary power died, I can't say anything.)

Don't Say

• 実際に語彙力が低い人に向かって「語彙力ないね」と言うのは失礼 (Saying 'you have no 語彙力' to someone who genuinely struggles with words is rude — slang use is self-directed)

Common Mistakes

• Using 語彙力がない to describe someone else's poor vocabulary — as slang it's always self-deprecating
• Not understanding it's a compliment in disguise — saying you've lost your words means something was incredibly impressive
