Following a train of thought


I was listening to an English conversation yesterday and had a question. The
speaker was having a conversation, and then suddenly made a comment that
didn't seem to relate to the previous topic.

I wanted to say, "I can't follow her train of thought" or "that conversation
doesn't seem to follow any train of thought.

I know that train of thought is 思考回路 but what very would you use for "follow"?
Not 従う right?




I think「付{つ}いて行{い}く」might be the word you're looking for.

> 彼女の話に **ついていけない**

  * It's hard to follow what she's saying

> 話し方に **ついていく** のが難しい

  * (Her) way of speaking is hard to follow
