Shape reportedly ruined view (9)
I believe the answer is:
rectangle
'shape' is the definition.
(rectangle is a kind of shape)
'reportedly ruined view' is the wordplay.
I cannot quite understand how this works, but
'reportedly' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
'view' could be 'angle' (angle is a kind of view) and 'angle' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for rectangle that I've seen before include "Shape of football pitch" , "Parallelogram with four right angles" , "box" , "regular sort of figure" , "Four sides involved in this" .)
