got과 gotten 둘다 get의 과거분사 입니다.

미국구어체에서 gotten을 많이 쓴다 합니다.

<got/gotten>

In sentences like "I've gotten tired of laugh tracks on situation comedies" "gotten" is the past participle of "get." Casual speakers in the U.S. often substitute "got"; but if you are striving for formal correctness, stick with "gotten." In British English, however, "got" is standard, and the older "gotten" has died, though not the related forms "forgotten" and "begotten."
