That's true. But "Tronna" is not so much a case of dialect as it is of sheer vocal laziness, in my opinion. Lazy ear and lazy tongue! (It's easier to just mumble two indistinct syllables than it is to clearly pronouce three. Much mangling of language appears to derive from this cause...vocal laziness, combined perhaps with not very attentive listening.)

Thus, in the modern day ghetto, the term "allright" has become merely..."'ite", and "do you know what I'm saying?" has become "know'msayn'?" (often added unnecessarily after every 2nd or third phrase, which causes its original purpose...brevity...to be defeated by repetitive redundancy!)

Likewise, "the neighborhood" is harder to say than "the hood", "Fro" is easier to say than "Afro", and "chair" is easier to say than going to the trouble of saying "chairman"...or the utterly ridiculous "chairperson".

In the latter case, however, we have mangling of language not through laziness, but through a desperate attempt to offend no one.

So we have reached the silly point in our culture where we call a chairman a piece of furniture in order to avoid possible gender-based misinterpretations and complications....and we now call actresses "actors" for some other silly damn reason along the same lines...thus causing the truly lovely word "actress" to vanish from usage. This does not help the cause of gender equality one bit, as far as I'm concerned, it just lessens the beauty and variety of the English language.

No wonder Chongo thinks Chimps are smarter than humans!
