"Your horse drinks the water."
Translation:Ton cheval boit l'eau.
can somebody please explain why "boit" and not "bouvez" i used vous in the translation instead of tu
Here, the subject of the sentence is "Your horse" (Informal: "ton cheval" or formal "votre cheval"), so the verb "boire" has to be conjugated at the 3rd person singular, which is "boit".

Please also have a look at this comment:
"Ton cheval boit de l'eau." would be "Your horse drinks (some) water".
"l"" is a definite article ("the" water in particular).
"de l'" is an indefinite article ("some" or "some of the" water).
