Talkaholic is a person who takes great pleasure in talking. A talkaholic has trouble keeping quiet and listening when other people are around.
Talkaholic指很喜欢讲话并且乐在其中的人，也就是我们所说的“话唠”。一般有别人在场的时候，话唠就很难做到不发言听别人说话。
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(购物狂)这两个词与talkaholic一样都是以-aholic为后缀的，这个后缀表示对某事有极度的兴趣，或者对某事上瘾。
For example:
Jane was a talkaholic who gave everyone her opinion whether they asked for it or not.
简就是个话唠，不管别人是否愿意听，她都要发表她的意见。
