请教一些向“'bout”之类的口语缩略词，谢谢

bout是缩略词？？？

Gotta
e.g. : I gotta go --> I've got to go

'Em
e.g. : Send all at once or spread 'em out --> Send all at once or spread them out

Lemme
e.g. : Lemme tell you this --> Let me tell you this

Y'all
e.g. : Damn y'all --> Damn ya' all --> Damn you all

Dunno
e.g. : I dunno what you mean --> I don't know what you mean

Whatcha
e.g. : Whatcha gonna do --> What are you going to do

bout好像不是缩写词啊~~
缩写词有：gonna=go to
wanna=want to
gimme=give me
