A few chasing female listener -- frightful (8)
I believe the answer is:
fearsome
'frightful' is the definition.
(thesaurus)
'a few chasing female listener' is the wordplay.
'a few' becomes 'some' (I've seen this before**).
'chasing' is a charade indicator (letters next to each other).
'female' becomes 'f' (abbreviation).
'listener' becomes 'ear' (I've seen this before).
'f'+'ear'='fear'
'some' put after 'fear' is 'FEARSOME'.
(Other definitions for fearsome that I've seen before include "Frightening, terrible" , "Horrendous" , "Formidable" , "Frightful" , "Of frightening appearance" .)
