Who possibly saved regularly and kept cash? (10)
I believe the answer is:
cheapskate
'who' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'possibly saved regularly and kept cash?' is the wordplay.
'possibly' indicates anagramming the letters.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'and' means one lot of letters go next to another.
The alternate letters of 'saved' are 'ae'.
'kept'+'cash'='keptcash'
'ae' put after 'keptcash' is 'keptcashae'.
'keptcashae' with letters rearranged gives 'CHEAPSKATE'.
Can you help me to learn more?
(Other definitions for cheapskate that I've seen before include "Miserly person" , "he won't pay the going rate" , "Mean type" , "Miserly type" , "One's tight" .)
