Fragrant smell drivers hold in memory (5)
I believe the answer is:
aroma
'fragrant smell' is the definition.
'aroma' can be an answer for 'smell' (synonyms). I'm unsure of the 'fragrant' bit.
'drivers hold in memory' is the wordplay.
I cannot quite understand how this works, but
'memory' could be 'rom' (ROM is an example) and 'rom' is found in the answer.
'drivers' could be 'aa' (I've seen this in other clues) and 'aa' is present in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for aroma that I've seen before include "Pervasive atmosphere" , "Test of knowledge" , "Scent - smell" , "Food fragrance" , "Agreeable odour" .)
