Recognises smell, on hearing of sight, taste or touch? (6)
I believe the answer is:
scents
'sight taste or touch?' is the definition.
I can't judge whether this definition defines the answer.
'recognises smell on hearing' is the wordplay.
'recognises' becomes 's' (I am not sure about this - if you are sure you should believe this answer much more).
'smell' becomes 'sense' (I've seen this in another clue).
'on hearing' shows a homophone (sound like).
'sense' sounds like 'cents'.
's'+'cents'='SCENTS'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for scents that I've seen before include "Fragrances, smells" , "Distinctive odours, usually pleasant" , "Trails" , "Essences and perfumes" .)
