A girl sounds pleased about followers (8)
I believe the answer is:
pursuers
'followers' is the definition.
(pursuer is a kind of follower)
'a girl sounds pleased' is the wordplay.
I cannot quite see how this works, but
'girl' could be 'sue' and 'sue' is found in the answer.
'sounds' could be 'purrs' (purring is a kind of sounding) and 'purrs' is present in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
'about' acts as a link.
Can you help me to learn more?
(Other definitions for pursuers that I've seen before include "Followers or chasers" , "They're followers of usurpers" .)
