Ring Vera on empty room for a stroke of swimming (7)
I believe the answer is:
overarm
'stroke of swimming' is the definition.
Both the definition and answer are adjectives. Perhaps you can see a link between them that I can't see?
'ring vera on empty room' is the wordplay.
'ring' becomes 'O' (letter resembling a ring).
'on' is a charade indicator (letters next to each other).
'empty' suggests removing the centre.
'room' with its middle removed is 'rm'.
'o'+'vera'+'rm'='OVERARM'
'for a' acts as a link.
Can you help me to learn more?
(Other definitions for overarm that I've seen before include "bowler's approach?" , "(Sportingly) with the hand brought forward above shoulder level" , "sort of service" , "Ma rover (anag.)" , "How to throw" .)
