Family member presents gold nugget hollowed out (4)
I believe the answer is:
aunt
'family member' is the definition.
(sister of a parent)
'gold nugget hollowed out' is the wordplay.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'hollowed out' says to hollow out the word (remove centre letters).
'nugget' with its middle removed is 'nt'.
'au'+'nt'='AUNT'
'presents' is the link.
(Other definitions for aunt that I've seen before include "Charley's in play?" , "Close relative" , "Wife of one's uncle" , "Uncle's wife" , "Charley's ___ , farce staged in London in 1892, revived and adapted ever since" .)
