Officer regularly devouring a hot snack (5)
I believe the answer is:
nacho
'snack' is the definition.
(I've seen this before)
'officer regularly devouring a hot' is the wordplay.
I cannot quite see how this works, but
'a' is found in the answer.
'hot' could be 'h' (abbreviation eg on taps) and 'h' is located in the answer.
'officer' could be 'nco' (abbreviation for non-commissioned officer) and 'nco' is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for nacho that I've seen before include "Hot snack" , "Mexican food item" , "Mexican bite" , "Mexican corn chip eaten with cheese, etc" , "Something consumed" .)
