you order, you tell (someone to do something), you are in charge, you call the shots
¿Puedes, cuando mandas en la rodilla del mendigo, mandar en su salud?
Can you, when you rule over the beggar’s knee, rule over his health?
— Henry V (1989)
Si tú me lo mandas, me iré contigo, pero no quiero.
If you send it to me, I’ll go with you, but I don’t want to.
— Nazarín (1959)
Si la mandas a hacer allá, lo vas a resolver tú.
If you have it made there, you'll be the one to handle it.
— Cidade dos Homens (2007)
