Ana revels in words.
The Flip Dictionary is a great thesaurus reference.
The word Yap lists the following:
babble, bark, bumpkin, chat, chatter, chodhopper, gab, gossip, hillbilly, jabber, lecture, prattle, rustic,
scold, yak, yammer, and yelp.
I never thought of Yap as a noun. This must be an old-fashioned meaning. (This bit of trivia might come in handy when writing historical stories or playing Jeopardy.)
