For every ache treated first for less money (7)
I believe the answer is:
cheaper
'for less money' is the definition.
I can't tell whether this definition defines the answer.
'for every ache treated first' is the wordplay.
'for every' becomes 'per' ('per' means 'for each' or 'for every').
'treated' indicates anagramming the letters.
'first' is a charade indicator (letters next to each other).
'ache' anagrammed gives 'chea'.
'per' put after 'chea' is 'CHEAPER'.
Can you help me to learn more?
(Other definitions for cheaper that I've seen before include "Not as dear" , "Comparatively despicable" , "Less extravagant" , "More reasonable" , "Less costly" .)
