Chap notices about energy in followers of Bacchus (7)
I believe the answer is:
maenads
'followers of bacchus' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'chap notices about energy' is the wordplay.
'chap' becomes 'man' (chap can mean a man).
'notices' becomes 'ads' (advertisements).
'about' is an insertion indicator.
'energy' becomes 'e' (physics symbol as in E=mca).
'man'+'ads'='manads'
'manads' going around 'e' is 'MAENADS'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for maenads that I've seen before include "frenzied females!" , "Frenzied women" .)
