My cat has unusual name: “Chichester”? (9)
I believe the answer is:
yachtsman
'chichester?' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see an association between them that I can't see?
'my cat has unusual name' is the wordplay.
'unusual' indicates an anagram.
'name' becomes 'n' (common abbreviation e.g. on forms).
'my'+'cat'+'has'='mycathas'
'mycathas' is an anagram of 'yachtsma'.
'yachtsma'+'n'='YACHTSMAN'
Can you help me to learn more?
(Other definitions for yachtsman that I've seen before include "Ainslie, for example" , "Member of sailing crew" , "(Recreational) sailor" , "I may go round the world" , "Leisure sailor" .)
