Concerned with Royal Mail covering area for delivery? (7)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
overarm
'area for delivery?' is the definition.
I can't tell whether this definition defines the answer.
'concerned with royal mail covering' is the wordplay.
'concerned with royal mail' becomes 'over' (I can't explain this - if you can you should give a lot more credence to this answer).
'covering' becomes 'arm' (arm is a kind of covering).
'over'+'arm'='OVERARM'
Can you help me to learn more?
(Other definitions for overarm that I've seen before include "Kind of bowling" , "One way to deliver" , "kind of delivery" , "How to throw" , "Like bowling in cricket" .)
