Angry at local feature of football pitch (8)
I believe the answer is:
crossbar
'feature of football pitch' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'angry at local' is the wordplay.
'angry' becomes 'cross' (cross can mean annoyed or angry).
'at' means one lot of letters go next to another.
'local' becomes 'bar' (one's local pub).
'cross'+'bar'='CROSSBAR'
Can you help me to learn more?
(Other definitions for crossbar that I've seen before include "Helps to define the goal" , "Post connecting goalposts" , "Top football goal" , "member over goal" , "one's seen on a bike?" .)
