Go pale: hint leg is broken (7)
I believe the answer is:
lighten
'go pale' is the definition.
Although both the answer and definition are verbs in their base form, I cannot understand how one could define the other.
'hint leg is broken' is the wordplay.
'is broken' is an anagram indicator.
'hint'+'leg'='hintleg'
'hintleg' with letters rearranged gives 'LIGHTEN'.
Can you help me to learn more?
(Other definitions for lighten that I've seen before include "lift" , "Illuminate" , "Become brighter" , "Get blonde" , "Make less dark or heavy" .)
