Any item used as a source of pleasure (7)
I believe the answer is:
amenity
'pleasure' is the definition.
(thesaurus)
'any item used' is the wordplay.
'used' is an anagram indicator.
'any'+'item'='anyitem'
'anyitem' is an anagram of 'AMENITY'.
'as a source of' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for amenity that I've seen before include "Any item (anag.)" , "Feature of place that makes living pleasant and convenient" , "Facility serving the public" , "Pleasantness" , "Pleasing facility" .)
