He shows his love three ways (4)
I believe the answer is:
owen
'he shows his' is the definition.
The definition suggests a singular noun which matches the answer.
'love three ways' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'three ways' becomes 'wen' ().
'o'+'wen'='OWEN'
Can you help me to learn more?
(Other definitions for owen that I've seen before include "Wilfred - - , WW1 poet" , "Welsh boy's name" , "English war poet, killed 1918" , "'E won over the Welshman" , "Clive --, English actor" .)
