A.E.I.O.U.

I am the type of person that does not like when people use language improperly. I hate when people mix up "them" and "those". I cringe when people say "aks" instead of "ask". Then there is the saying "not for nothing". What the heck does that mean? When people say, "I could care less" instead of "I couldn't care less" I feel like explaining that if you "could care less" it means that you do care. I was driving in my neighborhood the other day and I saw a sign for an Orthopaedic specialist. I hate when the "a" is added. Even this blog site is underlining it as incorrect spelling. Does the extra "a" make it seem more professional? It is the same thing with the words "color vs colour" and "honor vs honour". Stick to the regular way of spelling them. More vowels do not add anything to the meaning.
