College offering industrial training in an orange waiting room (11)
I believe the answer is:
antechamber
'waiting room' is the definition.
(I've seen this before)
'college offering industrial training in an orange' is the wordplay.
I cannot quite understand how this works, but
'college' could be 'tech' (technical college) and 'tech' is located in the answer.
'an' could be 'a' and 'a' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for antechamber that I've seen before include "Reception area" , "External room" , "room outside another" , "Waiting room" , "Small room before a larger one" .)
