Seaman who made his mark at Los Angeles? (6)
I believe the answer is:
lascar
'seaman who made his' is the definition.
'lascar' can be an answer for 'seaman' (I've seen this before). I am not sure about the remainder of the definition.
'mark at los angeles?' is the wordplay.
'mark' becomes 'scar' ('scar' can be a synonym of 'mark').
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'los angeles?' becomes 'la'.
'scar' put after 'la' is 'LASCAR'.
Can you help me to learn more?
(Other definitions for lascar that I've seen before include "E. Indian seaman" , "Kind of foreign sailor - quite a rascal" , "Asian sailor" , "Camp-follower" , "The East Indian sailor is a rascal" .)
