身邊有沒有這樣的朋友？他們不說話就難受，一張口說話就停不下來，什么事他們都有話說。嗯，這些朋友大概就是說話成癮，不說話難受的talkaholic吧。

Talkaholic is a person who takes great pleasure in talking. A talkaholic has trouble keeping quiet and listening when other people are around.
Talkaholic指很喜歡講話并且樂在其中的人，也就是我們所說的“話嘮”。一般有別人在場的時候，話嘮就很難做到不發言聽別人說話。

Similar words like workaholic and shopaholic are all ended with the same suffix -aholic, which means of an obsessive interest in something.
Workaholic（工作狂）和shopaholic（購物狂）這兩個詞與talkaholic一樣都是以-aholic為后綴的，這個后綴表示對某事有極度的興趣，或者對某事上癮。

For example:

Jane was a talkaholic who gave everyone her opinion whether they asked for it or not.
簡就是個話嘮，不管別人是否愿意聽，她都要發表她的意見。
