Bay attracts new hags (5)
I believe the answer is:
coven
'bay attracts new hags' is the definition.
I can't judge whether this defines the answer.
'bay attracts new' is the wordplay.
'bay' becomes 'cove' (I've seen this before).
'attracts' says to put letters next to each other.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'cove'+'n'='COVEN'
Can you help me to learn more?
(Other definitions for coven that I've seen before include "Witches' assembly" , "group for spells" , "Witches' set" , "Some wise women" , "Company of witches" .)
