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):

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
