I am a little unsure what と indicates in this sentence はい 、この マンション に 住んで いる と 思い ます.
Wow! I learned more Japanese today with this explanation than with anything else I did.
Very clear explanation thank you.
This と means, more or less, 'that'.
I think that he lives in this block of flats.
It's not related to と meaning 'and', but it's easy to tell them apart.
と meaning 'and' is between two nouns.
と meaning 'that' comes after a phrase and is followed by a verb such as 'say', 'think' or 'become'.
