Commonly Confused English Words

I'm about to flip out over the quality of beginners--and even of those who call themselves Writers. And all because I keep seeing the same word choice and spelling errors repeated in messages to other writers. Now, I could be way off base here, but I think its partly because those errant spellers see those same misspellings and misuses in others' posts, in mailing lists, on "author websites", and they either think the word are O.K. (words like 'definately') or expect the list or forum Mom to clean up after them. Sometimes Their Crankinesses complain about a lack of a spell checker in the systems, to which I point out a multitude of online services and the one built into their word processor. Is it so hard to handle a physical dictionary, anyway?

Take every opportunity to write well, and it will become automatic for you, cutting down on the amount of time you must spend editing your work. Do you really have such low self-esteem that you don't care what your peers think of your usual style? Are you content to spread the rampant degradation of the English language? I looked back through the last three years of posts here and noticed several on this issue. In the very beginning, I was ranting about these:

affect and effect (both as nouns and verbs)
rap and wrap
lie and lay (as verbs)
accept and except
allusion and illusion and delusion
censure and censor
compose and comprise
imply and infer
founder and flounder
loose and lose
expand and expend

To which I'm adding:

insight and incite

Please, spend some time with sweet Lady Dictionary, or hang out at the bar with Funk & Wagnall, and learn when to use each word and how to spell all of them correctly.
