Hi, I would regard this as being related to his autism. It is likely that he is using his available language to try and make conversation. But, given that you say he has a lot of learned language, the content doesn’t always make sense in the context. You could try working on his understanding and use of higher level language skills and also his conversational skills (Michelle Garcier Winner has quite a lot of material on perspective taking and conversational skills). All the best to you.
