Reduce the charge (7)
I believe the answer is:
cheapen
This might be a double definition.
'reduce' is the first definition.
(I've seen this in another clue)
'charge' is the second definition.
The definition and answer can be both related to change as well as being verbs in their base form.
Maybe there's an association between them I don't understand?
'the' acts as a link.
Can you help me to learn more?
(Other definitions for cheapen that I've seen before include "Cut" , "discount" , "Reduce the price of" , "Degrade (something)" , "Decry or devalue" .)
