Sometimes I use sound words (ummmm, mmmmmm, ahhhh - just to name a few) to express something that would take a lot more dictionary words to get the point across without them .... so, I have a few questions ..... answer any, all or make your own observations/comments/questions.

What sound words do you find yourself using most? or what combo(s) of sound words are your favorite?

Do certain sound words that sound the same, but get spelled differently - are they that way because they are being used by different people, or do you use both and they have different meanings? (ie ahhhhhhh and awwwwww)

When you use them in solid caps does that mean you would be saying them louder or with more emotion or both?

Do you find yourself using them more often in your written correspondence (IM's, EM's and PM's) or do you use about the same amount in similar verbal conversations?
