Questions & Answers about La professora vol que responguem avui i no demà.
Vol is the 3rd person singular present form of voler, meaning to want.
So:
- voler = to want
- vol = he/she wants
In this sentence, La professora vol... means The teacher wants...
Catalan normally uses vol que + subjunctive when one person wants someone else to do something.
So:
La professora vol respondre = The teacher wants to answer
(the teacher herself wants to answer)La professora vol que responguem = The teacher wants us to answer
(the teacher wants another subject, namely us, to do it)
Here que introduces the subordinate clause, roughly like that in English, even though English often leaves that out or uses wants us to... instead.
