Carrying on, Mother gets canteen in uproar (11)
I believe the answer is:
maintenance
'carrying' is the definition.
(thesaurus)
'mother gets canteen in uproar' is the wordplay.
'mother' becomes 'ma' (ma can mean mother).
'gets' says to put letters next to each other.
'uproar' indicates an anagram.
'canteen'+'in'='canteenin'
'canteenin' is an anagram of 'intenance'.
'ma'+'intenance'='MAINTENANCE'
'on' acts as a link.
(Other definitions for maintenance that I've seen before include "Running" , "Keep" , "Upkeep" , "What's done to preserve" , "bread and butter" .)
