I have collected some of short forms of English:
gonna=going to
gotta=a short form of ‘have got to’, ‘has got to’, ‘have got a’, or ‘has got a’
wanna=”want to” or “want a”
ain’t= a short form of ‘am not’, ‘is not’, ‘are not’, ‘has not’, or ‘have not’
Yep=yeah=yes
Nope=no
shan’t= especially British English “shall not”
won’t=will not
dunno=don’t know- I dunno
gimme=give me
outta=out of
'em=them
If someone knows more, please add them to the list…
Many thanks.
