Inedd ! ! choose the best spanish equivalent to the phrase. don't say that to your brother. (decir = to say, to tell) no digas eso a tu hermano. no decir eso a tu hermano. no digan eso a tu hermano. no digo eso a tu hermano.

No digas eso tu a hermano

It should be No digas eso a tu hermano. Because -as refers to you.

No digan eso a tu hermano mean do not say that to my brother, but is talking to more than one person.

No decir is just using that verb and doesn't usually work in a sentence.
No digo eso a tu hermano means that I do not say that to my brother.
