Been at march, lively? Wait here perhaps (11)
I believe the answer is:
antechamber
'lively? wait here perhaps' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'been at march' is the wordplay.
'been at march' can be anagrammed to 'ANTECHAMBER'.
Though, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for antechamber that I've seen before include "Waiting room" , "Small entrance room" , "Small room before a larger one" , "External room" , "Small room leading to a main one" .)
