Some smell I lack, required to appreciate this? (5)
I believe the answer is:
lilac
'to appreciate this?' is the definition.
The definition suggests a singular noun which matches the answer.
'some smell i lack' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'LILAC' can be found hidden inside 'smell i lack'.
'required' is the link.
Can you help me to learn more?
(Other definitions for lilac that I've seen before include "Light-purple" , "Spiritual knowledge" , "Shrub with fragment purple or white flowers" , "Shrub or small tree with fragrant blossom" , "Fragrant, pale purple flower" .)
