So I think so You said so . It means here as well ,the same as the before mentioned , ditto ! It is an agreement to what has been mentioned before by any other party ! He lives in Paris since 3 years . He doesn't speak French though . She knows him very well , she never greets him though. Here 'though' at the end of the sentence in the adverbial form means that what is mentioned in this part of the sentence contradicts or restrict what was mentioned before . It means nevertheless , however , in spite of ..

When someone says: "I told you so (!) " (for instance: I told you that it/this would end this way and you didn't believe me although I had told you it would) "I think so" ("Do you think David is coming to the party?" -> I think he is OR I think so) "David is a little bit shy but he is clever though" (like in French "cependant" or "neanmoins") "This soup is very spicy but I like it though" "it seems impossible, but you can try, though" I hope this helps.
