Old man put on Daphne's clothing for Eros (6)
I believe the answer is:
desire
'eros' is the definition.
(thesaurus)
'old man put on daphne's clothing' is the wordplay.
'old man' becomes 'sire' (I can't explain this - if you can you should give a lot more credence to this answer).
'put on' is a charade indicator (letters next to each other) (some letters go on or after others).
'clothing' suggests removing the centre.
'daphne' with its centre taken out is 'de'.
'sire' put after 'de' is 'DESIRE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for desire that I've seen before include "Want to reside?" , "Longing or wish" , "Reside in longing" , "Wish for strongly" , "Covet" .)
