すっごい

Wow, amazing! You're really good.
今日(きょう)すっごい(あつ)いね。
It's super hot today, isn't it?

すっごい is an emphatic variant of すごい created by inserting a geminate consonant (っ). This intensification pattern is productive in casual Japanese.

EMPHASIS PATTERN:

Japanese often intensifies adjectives by adding っ (geminate consonant):

  • すごい → すっごい
  • (おお)きい → おっきい
  • (ちい)さい → ちっちゃい

This is a casual spoken pattern and not used in formal writing.

ADVERBIAL USE:

Like すごい, すっごい is commonly used as an adverb modifying other adjectives or verbs, even though grammatically the adverbial form would be すっごく. In casual speech, the い-form is widely accepted as an adverb.

  • すっごい(たの)しい: super fun
  • すっごいおいしい: incredibly delicious

REGISTER:
Very casual. Common in excited speech among friends, especially among younger speakers. The emphasis conveys genuine enthusiasm.
