No, the hyphen is a punctuation mark, not a letter.
I know it isn't a letter, but I was wondering if it should be because you do see in words, especially some people's names.
You see apostrophes in words, too. They aren't letters either.
If the comma can be the 28th.
Duh, the ampersand (&) is already the 27th letter.
I do use it quite often, but I have enough trouble keeping up with new words that seem to pop up every week. Ha!
No, no sense in fixing something that isn't broken. lol
Thank you :-)
Letters tell you what to say, punctuation tells you how to say it
