Chatty,
I have Webster's New World, College Dictionary, 4th Edition:
1st word: gab
Then, GABA abbreviation for neurotransmitter
2nd word: gabardine
3rd word: gabble
4th word: gabbro, a dark coarse-grained rock; they smooth and use it to make tombstone! If googled, you'll see site, after site of pictures of it, etc.

So Chats, I don't understand, where you're coming from?
There's also a site called [Images of Gabbro Tombstone Pictures]!

But I'll let you or Ed3 or gims list the following letters, and that'll avoid any confusion...LOL!
