Divine young woman in towel commercial (5)
I believe the answer is:
dryad
'divine young woman' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'towel commercial' is the wordplay.
'towel' becomes 'dry' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'commercial' becomes 'ad' (abbreviation for advertisement).
'dry'+'ad'='DRYAD'
'in' is the link.
Can you help me to learn more?
(Other definitions for dryad that I've seen before include "butterfly" , "Beautiful young woman" , "minor divinity" , "Tree nymph" , "Nymph of the woods" .)
