1. (dependent) as if; in a manner suggesting that

   저 사람, 어디서 본 듯도 한데...

   Jeo saram, eodiseo bon deutdo hande...

   I suppose I might have seen him somewhere...

   강아지도 좋다는 듯 꼬리를 살랑인다.

   The dog gently wags his tail as if saying he's fine with it, too.

The dependent noun 듯 (deut) is used along with adjectival suffixes ㄴ (n), ㄹ (l), and 는 (neun).

Contraction of —듯이 (deusi, “as, like”). First attested in the Seokbo sangjeol (釋譜詳節 / 석보상절), 1447, as Middle Korean ᄃᆞᆺ (Yale: tos).

—듯 • (-deut)

1. as, like, in the same way that

   불 보듯 뻔한 일이다.

   Bul bodeut ppeonhan irida.

   It's as bright as seeing a fire. (It's very obvious.)

The suffix 듯 (deut) is directly appended to the suffix of a verb, an adjective, or 이다 (ida, “to be”), and if the stem ends in the consonant ㄹ (l), it does not drop out.
