Women’s drunken hen party crashed by maiden Daphne? (5,5)
I believe the answer is:
water nymph
'women's drunken hen party crashed' is the definition.
I can't judge whether this definition defines the answer.
'maiden daphne?' is the wordplay.
'maiden' becomes 'water' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'daphne?' becomes 'nymph' (daphne is a kind of nymph).
'water'+'nymph'='WATER-NYMPH'
'by' acts as a link.
Can you help me to learn more?
(Another definition for water nymph that I've seen is " Naiad".)
