Gold bag brought over containing small pen (6)
I believe the answer is:
austen
'pen' is the definition.
(Jane Austen - pen can mean a writer)
'gold bag brought over containing small' is the wordplay.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'bag' becomes 'net' (I've seen this in other clues).
'brought over' is a reversal indicator.
'containing' means one lot of letters goes inside another.
'small' becomes 's' (abbreviation - e.g. clothes size).
'net' in reverse letter order is 'ten'.
'au'+'ten'='auten'
'auten' enclosing 's' is 'AUSTEN'.
(Other definitions for austen that I've seen before include "Jane ......wrote Sense and Sensibility" , "Jane --, English author" , "Jane - - (lit.)" , "15 [JANE] the writer" , "English novelist, portrayed middle-class families" .)
