Spanish language Q&A Forum

When I first took this challenge, it skipped forward without giving the
opportunity of answering the question; so I just ended it and failed.
One is not allowed to go back a page.  Is there another choice that
can be made in the event of this happening?

Why does should have done [something] use the present conditional rather than the perfect conditional?

This lesson says:

"In Spanish, to express that someone "would have [done something]" in the past, we use the auxiliary verb haber.

Haber [ìn the conditional simple] + participle of main verb"

However wouldn't you use the perfect conditional to say "would have"?

Note that the construction tal vez (maybe) accepts the indicative and the subjunctive moods with no change in meaning.

What do you mean with the "maybe" after tal vez? 

I came to this lesson from the quiz question:

Marta y yo ________ 200 km a la semana para ir a trabajar. Marta and I travel 200 km a week to go to work.(HINT: Conjugate "hacer" in El Presente)
Answer was “hacemos”, but I was expecting an explanation on why the verb “hacer” (to make) is applicable to what in English would be “travel”.

Why does this sentence have "lo"? Doesn't dejaron todo mean they left everything?

I have done two tests now where I have chosen "estaba imprimido", but it tells me I've chosen "estaba imprimiendo", so it is counted as an error.  I don't know why that is happening.  

Is this true for all regular verbs (-ar, -ir, -er)?

When do you use por in sentences and not para

For the phrase: Van (Uds.) a enviar los premios a nosotros?

To answer this question negatively, would it become:

no nos vamos a enviarlos

no nos los vamos a enviarlos (does the combination of nos + los clash because of the similar sounds)

Thank you!
