Divine females are entering new conveniences (6)
I believe the answer is:
naiads
'divine females' is the definition.
The answer and definition can be both people as well as being plural nouns.
I also know that 'females' relates to this answer.
'are entering new conveniences' is the wordplay.
'are' becomes 'a' (short for 'are', historical unit of measurement).
'entering' means one lot of letters goes inside another.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'conveniences' becomes 'aids' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'n'+'aids'='naids'
'a' placed within 'naids' is 'NAIADS'.
Can you help me to learn more?
(Other definitions for naiads that I've seen before include "Classical water nymphs" , "Water-nymphs" , "Sprites" , "Water nymphs - sad Ian (anag)" , "Female swimmers" .)
