Having skill, he gets one right (3)
I believe the answer is:
art
'having skill he' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'one right' is the wordplay.
'one' becomes 'a' (a thing is one thing).
'right' becomes 'rt' (abbreviation as in Rt Hon- the Right Honourable).
'a'+'rt'='ART'
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for art that I've seen before include "Creative works; knack" , "Trickery" , "Skill in a specified thing" , "eg Painting" , "Work such as painting or sculpture" .)
