Clearly your a bunch of idiot's and looser's. Rule's are their too be followed, that i's why their called RULE'S. Alot of writer's get it wrong at first, than they realize their udder moran's in the first place. Jame's Joyce come's to mind, a's well a's Samuel Clemen's, Edward S. Aaron's, and Julia Gla'ss. Both where idiot's!
Now to relax and poor myself some Chabli's -- my whine of choice.
Well, the first 2 are really from spoken dialect--which could take us very far afield. The latter 2 strike me as the result of insufficient phonics--ie, listening to others speaking and to one's own speaking. I had never seen 'moran' until the last few months and now seem to notice it often enough that I have a immediate "oh, that's the becoming common mis-spelling" reaction.
I had a co-worker who wrote "probaly" all the time. I prefer "prolly" just because of an obscure line delivered by Judge Reinhold in Fast Times ("I'll talk to Dennis Taylor; I can prolly get you in"). Movie version of course, not the original book (which I have, somewhere...)
