1.) Take the "g" off of the ending "ing" and if you want replaced with an apostrophe
ex: playing = playin'
soaking = soakin'
2.) Replace the "th" at the beginning of a word with 'd'
ex: there = dere
that = dat
3) You does not always get replaced by ya, it depends on the sentence
ex: "Whea're ya goin'?"
4) The sound "-ther" would be replaced with "dah" in words such as mother (muddah), and another (anuddah)
5) The "er" ending is replaced by "a." This is very common in the word "paper" which the Newsies call "pape" but sometimes "papah."
6) Another replacement: "er" sound is replaced with an "oi" sound-
ex: work = woik
girl = goil
perfect = poifect
person = poison
7) Some random changes that i can't really describe or put into definition:
talk = tawk
New York = New Yawk
coffee = cawffee (yes yes, we all kno that one!)
board = bwoard
8) Just a lil note, a "w" on the end of a word is kinda taken off so the word has a harder ending. An example of this would be snow. Try not pronouncing the "w."
