Women’s hen party reorganised to include Mike and Daphne, perhaps (5,5)
I believe the answer is:
water nymph
'daphne perhaps' is the definition.
I can't judge whether this defines the answer.
'women's hen party reorganised to include mike' is the wordplay.
'women' becomes 'w' (standard abbreviation).
'reorganised' is an anagram indicator.
'to include' means one lot of letters goes inside another.
'mike' becomes 'M' (phonetic alphabet: alpha, bravo, charlie etc.).
'w'+'hen'+'party'='whenparty'
'whenparty' is an anagram of 'waternyph'.
'waternyph' enclosing 'm' is 'WATER-NYMPH'.
'and' is the link.
Can you help me to learn more?
(Another definition for water nymph that I've seen is " Naiad".)
