Over-lenient — glut in end unfortunately (9)
I believe the answer is:
indulgent
'over-lenient' is the definition.
I can't judge whether this defines the answer.
'glut in end unfortunately' is the wordplay.
'unfortunately' indicates an anagram.
'glut'+'in'+'end'='glutinend'
'glutinend' with letters rearranged gives 'INDULGENT'.
Can you help me to learn more?
(Other definitions for indulgent that I've seen before include "Tolerant, lenient" , "Compliant" , "Too tolerant or generous" , "passing over faults" , "Ready to gratify the wishes of others" .)
