Face up to change - it may be refreshing (3,2,3)
I believe the answer is:
cup of tea
'it may be refreshing' is the definition.
The definition suggests a singular noun which matches the answer.
'face up to change' is the wordplay.
'change' is an anagram indicator.
'face'+'up'+'to'='faceupto'
'faceupto' with letters rearranged gives 'CUP OF TEA'.
Can you help me to learn more?
(Other definitions for cup of tea that I've seen before include "Face pout (anag.)" , "The English panacea" , "Our national panacea - personal field of interest" , "Hot drink" .)
