Thread: Some simple translations..

Hi Wendykay,

You use the infinitive form after prepositions. Por is a preposition, but por favor is not.

You use subjunctive for formal commands.

Por favor, dí a Tia Isabella que digo hola. (informal)
Por favor, diga a Tia Isabella que digo hola. (formal)

But, I think you might want to use the verb saludar, as in
Por favor, salude a Tia Isabella. (formal)
Por favor, saluda a Tia Isabella. (informal)

In "Please, pack the boxes and mark them" the command form would be:
Por favor, empaque las cajas y márquelas. (formal)
Por favor, empaca las cajas y márcalas. (informal)

Disclaimer: I'm a student of Spanish. Let's both wait for confirmation from a native speaker.

Hi all,
just a little observation. We don't usually say
di hola a X in Spanish...unless we are talking to a kid, for example and right in front of the person we are asking him to say Hi/Hello to the other person. Teaching the kid some manners and education.
In the example below, we just say
Saluda a X de mi parte/ Mándale saludos a X de mi parte.
The rest of the sugestions are fine.
