One revealing article about holidaymaker killing love (8)
I believe the answer is:
naturist
'one revealing' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'article about holidaymaker killing love' is the wordplay.
'article about' becomes 'na' (I can't justify this - if you can you should give a lot more credence to this answer).
'holidaymaker' becomes 'tourist' (synonyms).
'killing' suggests deleting specific letters.
'love' becomes 'o' (love means zero in tennis).
'tourist' with 'o' removed is 'turist'.
'na'+'turist'='NATURIST'
Can you help me to learn more?
(Other definitions for naturist that I've seen before include "One who believes in going nude" , "One exposed" , "One abandoning clothes" , "person without clothes" , "one barely feeling comfortable" .)
