Since i’ve been ill and unable to keep up with individual replies, i will offer thanks and so forth all at once, and hope that some dialogue can continue.
First, i would not have guessed that this topic fit IMHO best, but if i had i certainly would have posted it there. i like to do things correctly. Next, regarding the term orthography: i am aware that there are many more specific fields of language study, and also that it’s an outdated expression. i apologize for being unclear. originally i used it to mean the field of spelling, but understand it to cover other aspects of the writing process. i am probably more specifically interested in etymology and spoken dialect, however, i believe it’s best to begin from a “macro” point of view, and then narrow my focus as i gain a more complete understanding of the whole picture.
I have heard of a few of the books/authors mentioned, and am so appreciative of all your recommendations. of course it’s a huge field with many subsections, and that’s why i asked for advice. i have been reading Straight Dope since before it was on the net, and have always been impressed with the thought-out commentary of the Teemings.
And finally, yes, Wendell, i do understand how difficult it would be to study these subjects. i only attended college until the money ran out, which was sooner than anyone would hope, and my focus at that time, silly child that i was, revolved around Political Science. when i am able to return to serious study, i plan to focus on linguistics and English; as you say, history and development are imperatives. i assure you i am up to the challenge.
but in the meantime, gaining as much background knowledge as possible is my key, and i’m looking forward to finding books mentioned here.
thanks ever, ever so much,
mary
