They can cope with costs cannily (5)
I believe the answer is:
scots
'they can' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'cope with costs cannily' is the wordplay.
'costs' can be anagrammed to 'SCOTS'.
But, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for scots that I've seen before include "- Greys, - pine" , "Language of Burns" , "Folk from Fife" , "Glaswegians, Aberdonians etc" , "A UK language" .)
