Talkiness → It is formed from "talk" (from Old English *tælcian*, meaning to speak or discuss) and "-iness" (a suffix meaning the quality of being). The word "talkiness" refers to the quality of being talkative or inclined to talk a lot.
Think of the act of 'speaking' ('talk') and the quality of that action ('-iness') — that's why talkiness means the quality of being talkative.
