Name abstainers – following one, a particular mess (5)
I believe the answer is:
naafi
'a particular mess' is the definition.
'naafi' can be an answer for 'mess' (I've seen this before). I am not certain of the 'a particular' bit.
'name abstainers following one' is the wordplay.
'name' becomes 'n' (common abbreviation e.g. on forms).
'abstainers' becomes 'AA' (Alcoholics Anonymous).
'following' becomes 'f' (used when citing page numbers etc).
'one' becomes 'i' (Roman numeral).
'n'+'aa'+'f'+'i'='NAAFI'
Can you help me to learn more?
(Other definitions for naafi that I've seen before include "place for force-feeding?" , "Army canteen/shop" , "Caterers" , "Forces' canteen/shop" , "military institution" .)
