  • Next, a reader who doesn't know English too well reads the sentence. Hmm, what does this word 'sum' mean? He checks the dictionary. He re-reads the sentence. He knows what all the words mean but can make no sense of the sentence.

    Actually, he'll probably see that "sum" in the dictionary is a noun, whereas it's being used in a sentence as an adjective and he will remain unable to decipher the message, but for an entirely different reason. :)

    Indeed, nor do I. This subject comes up over and over again on Usenet, the same arguments for and against are trotted out each time, but the conclusion is usually this:

    If everybody posting to an English language forum makes their best effort to write comprehensible English then everybody benefits.


    I don't spend much time on Usenet, so I wasn't aware that this was a re-hash. Anyhow... I can agree with your conclusion that people should make their best effort at proper English. I certainly have some of my own language pet peeves. I just thought I'd try and see what everyone thought the big deal was. Thanks for entertaining the debate.
