I have heard it pronounced both ways but I don't know which one of them is correct. I think I like going better myself. I'm from asia.
Going? or goign?
i use them both....not on purpose just typos....but hey whatever works for you people
Most of the time, at least in casual speech, it's pronounced as "gonna", as in "I'm gonna be there at 4:30."
The ending of "going" is never pronounced to rhyme with "sign". Rather it rhymes with "sing" or "sin", or in some dialects "seen".
I have heard of English dialects having [IN], [In], [iN], and [in] for the last syllable of "going", but I have *never* heard of an English dialect having [aIn] (or equivalent) for the last syllable of "going".
