"Let her know."

Translation: Deixa ela saber.

[light-rider]

I gave the answer "Deixa-a saber." The system response was: You used the command form "deixa-a" instead of the ele/ela form "deixe-a". The two correct translations given were "Deixe-a saber" and "Deixa ela saber." Was I really wrong to use the command with a?

[Paulenrique]

yes, you can use "deixa-a", but that's rare, also cause of the connectionm"a-a" that make it one sound!,so, using "deixe-a" is better.

[light-rider]

Ah! That's very helpful, thank you!

"deixa saber a ela" does not work

Why the hyphen?

[Complex77]

Why not "deixa lhe saber"?

[gaih]

I'll give it a try: 1) her is a direct object rather than an indirect one hence lhe is not appropriate; 2) lhe should be used ahead of the verb of which it is the indirect object, or you needs the hyphen "verb-lhe" more European style.

The dictionary says that deixar takes direct pronoun after it: "deixar alguém louco" to drive someone crazy.

[Philip_Petit]

Yep, you make sense!

[Dr.Fandey]

Yeah, why?!

[MattBenet]

Why not Deixa ela conhecer?

[GrannySlasher]

Would the "deixa" change to something else if it was "them", "us" or "me" following it?
Also, why are both "deixa" and "deixe" allowed in this sentence?
