Bristly customer finding love in boozer (4)
I believe the answer is:
boar
'bristly customer' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'love in boozer' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'in' means one lot of letters goes inside another.
'boozer' becomes 'bar'.
'o' inserted into 'bar' is 'BOAR'.
'finding' acts as a link.
Can you help me to learn more?
(Other definitions for boar that I've seen before include "Resting place for birds or bats" , "Wild animal, sounds like drill" , "Uncastrated male pig" , "Uncastrated male hog" , "The head for drink Falstaff had" .)
