Garment held by a poor actor in Lincoln? (7)
I believe the answer is:
abraham
'lincoln?' is the definition.
(synonyms)
'garment held by a poor actor' is the wordplay.
'garment' becomes 'bra' (bra is a type of garment).
'held by' means one lot of letters goes inside another.
'poor actor' becomes 'ham' (ham can mean a bad or over-the-top actor).
'a'+'ham'='aham'
'bra' put within 'aham' is 'ABRAHAM'.
'in' is the link.
(Other definitions for abraham that I've seen before include "Father of all the Jews (7)" , "name" , "Old Testament patriarch" , "Bar a ham from playing the Biblical patriarch" , "E.g. Lincoln" .)
