Essentially, it has rosy associations (5)
I believe the answer is:
attar
'it has rosy associations' is the definition.
The definition suggests a singular noun which matches the answer.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for attar that I've seen before include "Rose petal oil" , "Essential oil from flowers" , "Fragrant rose oil" , "Fragrant oil obtained from roses" , "Fragrant oil obtained from floweres" .)
