Description of window and broken doorframe oaf removed (6)
I believe the answer is:
dormer
'description of window' is the definition.
'dormer' can be an answer for 'window' (dormer window is a kind of window). I'm not sure about the 'description of' bit.
'broken doorframe oaf removed' is the wordplay.
'broken' indicates an anagram.
'removed' is a deletion indicator.
'doorframe' with 'oaf' taken out is 'dorrme'.
'dorrme' is an anagram of 'DORMER'.
'and' is the link.
Can you help me to learn more?
(Other definitions for dormer that I've seen before include "Light" , "Kind of window under gable" , "Window under gable on sloping roof" , "Window fitted vertically onto a sloping roof." , "Window projecting vertically from a sloping roof" .)
