How to use it

The て-FORM of 「~ぶる」: connects into the next action. Critical tone.

  • 「~ぶって」 connects into a following action: "putting on an act of A, then…". Very common phrase: 「知ったかぶって」 (acting like a know-it-all).
  • Same root as 「~ぶる」/「~ぶった」; this is the connecting form.
  • Always carries a critical tone toward a fake attitude.

Examples

  • He acted like he knew and then gave a wrong explanation.

  • He puts on airs and just gives orders, so everyone resents it.

Keep in mind

  • A clause-connecting form (te-form).
  • A commonly seen phrase: 知ったかぶって.

Common mistakes

  • Wrong知(し)らないふりをしてぶっていた。

    He was acting like he already knew.

    Correct知(し)ったかぶっていた。

    「ぶる」 must attach DIRECTLY to a noun/adjective (知ったか+ぶる), not stand alone.

  • Wrong謙虚(けんきょ)ぶって、みんなに好(す)かれた。

    He put on a modest act, and everyone ended up liking him.

    Correct謙虚(けんきょ)ぶって、かえって反感(はんかん)を買(か)った。

    「ぶって」 carries a CRITICAL tone (fake), so the following clause is usually a negative consequence.

Exam tips

  • 「ぶって」 = the て-form of 「ぶる」 (connecting clauses); common phrase 「知ったかぶって」.
