English sovereign is living frugally (5)
I believe the answer is:
eking
'is living frugally' is the definition.
I can't judge whether this defines the answer.
'english sovereign' is the wordplay.
'english' becomes 'E' (abbreviation).
'sovereign' becomes 'king' (king is a kind of sovereign).
'e'+'king'='EKING'
Can you help me to learn more?
(Other definitions for eking that I've seen before include "Managing to make (a living)" , "Making last longer by careful use" , "spinning?" , "making up the required amount" , "With difficulty, making" .)
