Ok, I did ask a Latvian friend about this but he didn't seem to either know or understand what I meant. Hopefully somebody here can..
So you have the conjugations for example
Es lasīju grāmatu.
Es lasu grāmatu.
Es lasīšu grāmatu.
But then if I was to say Es lasīšu grāmatu. "Then I'm going to watch TV" - Do you conjugate the rest of the sentence or just the first part? I've just looked all through the forum here, clicked any links that seemed useful but most of the links are dead.
