Early Australian with derivation in Lincoln? (9)
I believe the answer is:
aborigine
'early australian' is the definition.
(I've seen this before)
'derivation in lincoln?' is the wordplay.
'derivation' becomes 'origin' (origin is a kind of derivation).
'in' means one lot of letters goes inside another.
'lincoln?' becomes 'abe' (Abraham Lincoln).
'origin' placed within 'abe' is 'ABORIGINE'.
'with' is the link.
(Other definitions for aborigine that I've seen before include "Early Australian" , "I was in Oz first"" , "Native Australian" , "Old Australian" , "Original inhabitant" .)
