Flap of skin or hide at the end (6)
I believe the answer is:
furore
'flap' is the definition.
(thesaurus)
'skin or hide at the end' is the wordplay.
'skin' becomes 'fur' (fur is a kind of skin).
'at the end' suggests the final letters.
The last letter of 'hide' is 'e'.
'fur'+'or'+'e'='FURORE'
'of' is the link.
(Other definitions for furore that I've seen before include "Sudden outburst, uproar" , "Uproar, outcry" , "A general uproar or noisy scene" , "Outbreak of public anger or excitement" , "Turmoil, uproar" .)
