兩個人端著茶隨口聊天的那種狀態：沒有議題、沒有目的，話題自己一句接一句地滑過去，講的人放鬆，聽的人也不用緊張。chatty 抓的就是這個「輕鬆閒聊」的氣氛。有趣的地方在於，這股氣氛不一定要從嘴巴出來——它同樣可以從一頁文字裡飄出來。From the word’s history
From chat + -y. Chat is a clipping of Middle English chateren 'to chatter', an imitative word — it copies the sound of quick, light talk.
chatty 是 chat 加上形容詞字尾 -y。chat 又是從中古英語 chateren（喋喋不休）截短來的，而 chateren 本身是擬聲字，模仿的就是那種又快又輕的說話聲。所以這個字從根上就不帶「講重要的事」的味道，它記錄的是聲音的質地：輕、快、連續、不費力。
