The anxieties of fatheaded listeners (5)
I believe the answer is:
fears
'the anxieties' is the definition.
(fear is a kind of anxiety)
'fatheaded listeners' is the wordplay.
'fatheaded' becomes 'f' (this could be a standard abbreviation which I don't know about).
'listeners' becomes 'ears' (body parts which listen).
'f'+'ears'='FEARS'
'of' is the link.
Can you help me to learn more?
(Other definitions for fears that I've seen before include "Apprehensions" , "Concerns, dreads" , "Is afraid of" .)
