Issuing commands in spanish questions

[bobjenkins]

I'm going to a type a few commands can you please correct them if neccessary? I've had a bit of trouble with these.
I've bolded the main parts so its easier for you :)
__________________________________________________ ___
lets just say "it" is a "el libro"

- to a good friend (informal) / tú

Cómpralo - "buy it"
(drop the final "s" add the pronoun, ect. And is the accent in the right place??)

(Tú) no lo compres - "Dont buy it"
(in the negative informal the verb comprar takes the subjunctive form??)


__________________________________________________ ____
- to good friends (informal) / vosotros

Cómpradlo - "buy it"
(take the infinitive and replace the final "r" with a "d" /again is the accent in the right spot, also is the pronoun in the right spot? It just sounded a little strange to have a pronoun after a "d" so I wasn't sure)

(Vosotros) no lo compreís - "dont buy it"
(uses subjunctive form??)

__________________________________________
As far as I could tell every thing in the imperative (command) mood uses the present subjunctive form of the very, except in the

Affirmative Tú
and
Affirmative Vosotros

¡Muy bien!

(Tú) no lo compres - "Dont buy it"
(in the negative informal the verb comprar takes the subjunctive form??)
¡Perfecto!Yes, it takes the subjunctive form

Wrong: the stress falls on the /a/: Compradlo (without the accent)

(Vosotros) no lo compreís - "dont buy it"
(uses subjunctive form??)

Sorry, it's wrong again: No lo compréis.
It uses subjunctive form.

we learned about the commands too....for 3 or more syllables the accent mark is on the 1st syllable vowel. 4 syllable words have the accent on the 2nd syllable vowels.

did you learn about the irregular forms?

Decir -> di
hacer -> haz
poner -> pon

just some info :P irmamar already corrected it for you :)

we don't use the vosotros form, by the way

[irmamar]

You don't use "vosotros", but you have to say "you all" or "you both", isn't it the same?

[bobjenkins]

jchen, Im no expert but in all the books I have they say vosotros is only used in spain. Anyone from spain that can confirm this? Otherwise I wont focus on it too much if no one uses it :)

@irmamar: we use ustedes which is "you all" or "you both" as well

@bobjenkins: hmmm yeah I think vosotros is only used in Spain also

Well, if nearly 45 million people is "no one".... and you don't ever expect to talk to Spaniards, travel to Spain or read/write a Spanish text then you'll have no problem. ;)
Of course, I'm biased. I have had to use it.
:D
