How we know use leest or lezen....?
The verb changes depending on the subject.
"Je spreekt" - is that a correct sentence?

They both mean the same (the) but are used for different words. The majority of dutch words will use de rather than het though. This link should be a good one to help learn the when to use either: https://forum.duolingo.com/comment/3732938
