Actually, you quite missed the point confused ; etymological searches are always informative and relevant; however, in and of themselves, they are not all-encompassing dogma when considering the evolving use of terms / phrases, particularly allowing for colloquialisms, regionalisms, connotations and the more than occasional malaprop.
It seems that you would do well to delve into lexicography in more depth; I'd suggest starting with innovative concepts promoted by PW Hanks, who focuses on, amongst other aspects, convention v. creativity and innovation with regard to meaning.
Glad for the discourse; sorry if you're torqued, dismayed bewildered or even the least bit intransigent.
