"You love us."

Translation: Nos amatis.

[Magister_Smith]

"you" is not specified as singular or plural. "amas" should also be accepted.

[Blas_de_Lezo00]

Nos amas is also correct.

[danielgama18]

why is "Tu nos amatis" wrong?

[Magister_Smith]

“-tis” is a plural ending (for you all). So you would need “vos nos amatis (plural)” or “tu nos amas (singular).”
