Hello, hopefully a quick and easy question.... When writing dialogue, I tend to sound it out in my head how I expect the character to speak, which sometimes includes actually saying it myself. I modeled one side character on myself, her speech patterns anyway, and she's a tad sarcastic... In response to a friend she says what sounds like "chh" or "chuh" or "cha", which is a hybrid of "yeah" and the "chhh" sound of disapproval. Maybe this is a colloquialism (Philadelphia) for myself, but it works for the character so I'd like to use it. I don't know if I should just go ahead and spell it, in italics because it's a sound not a word, "cha" which I have seen... once... online (did a google search), OR if there is an actual known spelling for that expression. Probably doesn't matter in the end but I figured I'd ask!
