When I was about seven years old, living in S. California, I noticed in school one day that "there weren;t nor r in warsh. I praqcticed say waaash for quite some time, and at that point I was losing my Missouri accent. Now I have none whatso ever, but I can still get down in the accent with people in the family when need be.
Since then I studied other languages, I learned Hebrew well enough to read the Word in Biblical Hebrew, I majored in French literature at the U of I Champaign-Urbana, and managed to be on the Dean's list, finally, here in Spain I have picked up on a lot of Spanish to the point I am able to talk real estate talk, bank stalk, and more.
My point is, being absolutely correct here in the Forum is just fine if you are, but if anyone here is able to make himself, herself, understood, please leave them alone. Somewhere in the Word it is written that people will teach with halted speech and sstammering. I seem to understand everyone here, though many times it may hurt. Yes, language is important but understanding trumps perfect language every time. Praise God, He is worthy, not we.
