Apart from the literal meaning, it can be a way of saying "we're on good terms" or "we get along". Ex. How are John and Mary doing? --They've had some tough times, but they're talking now (=they're getting along now).

Hi 李翠屏, Basically, it means there is 2-way communication happening. "We are talking" can mean different things in different situations. A little boy walks to his parents and asks for a snack. The mother and father are having an important conversation. Mom says: "Just a minute sweetie, your dad and I are talking." (they are communicating, busy, the boy needs to be patient) A company lawyer asks another company lawyer about work. "Did your company buy that other company?" "Not yet, we just started talking." (communication recently began between the 2 companies) A woman asks her friend about the friend's love life. "Are you dating these days?" "Dating? No. There's a guy at my gym that I think is cute, but right now we're just talking." (They're just communicating, they haven't gone on a date yet.) There are also some funny situations where there is talking...without talking! https://www.youtube.com/watch?v=CejhQC9hUO8 https://www.youtube.com/watch?v=_JmA2ClUvUY I hope that helps! If you tell me the context of your example maybe I can help more.

In America, sometimes this is slang for when 2 people are dating, but they don't want to make the relationship official.

This phrase is generally used to indicate an improvement in a situation. It means that things have gotten better or more interesting. 这个表达类似于汉语里的 “这才像话“ ”这才对嘛” “你早说不就得了” -I heard American will resume executions of death row inmates. -Now we are talking. -我听说美国将要恢复死刑了。 -这才像话嘛！ -I think we should stop gossiping about their divorce. -Now we're talking! -我觉得我们不应该继续对人家离婚的事说三道四了。 -这才对嘛！赞同！
