Drill order to put up with a taunt (5,2,4)
I believe the answer is:
stand at ease
'drill order' is the definition.
'stand at ease' can be an answer for 'order' (I've seen this before). I am not certain of the 'drill' bit.
'put up with a taunt' is the wordplay.
'put up with' becomes 'stand' (both can mean to tolerate or bear).
'taunt' becomes 'tease' (synonyms).
'stand'+'a'+'tease'='STAND AT EASE'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for stand at ease that I've seen before include "order to relax" , "take a relaxed attitude" , "letting attention go?" , "Relax (on parade ground)" , "Instruction to soldiers - and sea state (anag)" .)
