Wet implement with value (5)
I believe the answer is:
douse
'wet' is the definition.
(dousing is a kind of wetting)
'implement with value' is the wordplay.
'implement with' becomes 'do' (I am not sure about this - if you are sure you should believe this answer much more).
'value' becomes 'use' (Use is a type of value in economics).
'do'+'use'='DOUSE'
Can you help me to learn more?
(Other definitions for douse that I've seen before include "Throw water over, extinguish" , "Of fire, quench with water" , "can make you really wet" , "Plunge into water" , "duck in water" .)
