Asking questions at a sitting? (6)
I believe the answer is:
posing
This might be a double definition.
'asking questions' is the first definition.
'posing' can be an answer for 'asking' ('pose' can be a synonym of 'ask'). I'm not sure about the 'questions' bit.
'a sitting?' is the second definition.
('posing' can be a synonym of 'sitting')
'at' acts as a link.
Can you help me to learn more?
(Other definitions for posing that I've seen before include "About to be shot, perhaps" , "Assuming a certain position" , "Assuming an attitude" , "putting on an act" , "puzzling" .)
