I am certainly not alone.
Does it cause you to cringe when, in conversation, someone will mis-use (or abuse) a word; based solely on a bad habit?
I have seen well educated people use very stupid phrases with authority.
Some of my favorites are listed in a post on My Blog.
They include:
Supposively,
Irregardless,
Unloosen

And in correspondence it is far to prevalent to see 'loose' where it should be 'lose' and 'myself' where it should be 'me'.

What are the ones YOU find most irritating?
