Family, edgier unfortunately, following gym (8)
I believe the answer is:
pedigree
'family' is the definition.
(thesaurus)
'edgier unfortunately following gym' is the wordplay.
'unfortunately' is an anagram indicator.
'following' says to put letters next to each other.
'gym' becomes 'pe'.
'edgier' is an anagram of 'digree'.
'digree' put after 'pe' is 'PEDIGREE'.
(Other definitions for pedigree that I've seen before include "Genealogical table" , "Ancestry of a purebred animal" , "Lineage, ancestry" , "Of animals, recorded line of descent" , "Ancestry - genealogy" .)
