Tolerant fellow and striking girl doing a bunk (7)
I believe the answer is:
lenient
'tolerant' is the definition.
(similar in meaning)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lenient that I've seen before include "Showing tolerance" , "Light" , "Soft-hearted" , "Not severe in punishing" , "Tolerant, merciful" .)
