Spanish language Q&A Forum

If I'm correct, it appears from the quiz that "aquel" and the  equivalent "todo aquel que" forms have identical meanings.  Would it be worth adding a note in the lesson to clarify that "todo aquel que" is simply another alternative? 

Where does the word "Librólogo" come from, please? Is it a play on the word Librero/a?

A quiz question asks “vas a venir al cine mañana?”. In English it seems more common to say “are you going to go the movies tomorrow?” (or simply “are you going to the movies tomorrow?”) Any insights into this use of venir instead of ir?

What are the equivalents for can't & must not for logical conclusions in Spanish? That is, how can I express the difference in meanings given in the following examples?

(present)

The restaurant can't be open - the door is locked

The restaurant must not be any good - it is always empty

(Past)

He had left the office at 6:00 p.m. He can't /couldn't have been at home at 6:05 p.m

She was not answering the doorbell. She must not have been at home then.
