Love, austere, without wanting smell (9)
I believe the answer is:
odourless
'smell' is the definition.
(I have seen 'Lacking smell ' mean 'odourless' so perhaps 'smell' could also mean 'odourless')
'love austere without' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'austere' becomes 'dour' (I can't justify this - if you can you should believe this answer much more).
'without' becomes 'less' (I've seen this in another clue).
'o'+'dour'+'less'='ODOURLESS'
'wanting' acts as a link.
Can you help me to learn more?
(Other definitions for odourless that I've seen before include "devoid of smell" , "not raising a stink" , "Lacking smell" , "descriptive of clean air" , "Unscented" .)
