Wall part beginning to bend in high wind (5)
I believe the answer is:
gable
'wall' is the definition.
(gable wall is a kind of wall)
'beginning to bend in high wind' is the wordplay.
'beginning to' suggests taking the first letters.
'in' is an insertion indicator.
'high wind' becomes 'gale' (I've seen this before).
The first letter of 'bend' is 'b'.
'b' put into 'gale' is 'GABLE'.
'part' acts as a link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for gable that I've seen before include "US actor" , "Clark ___, film actor, d. 1960" , "screen legend" , "Roof structure" , "American actor" .)
