American name for "second-hand" (4)
I believe the answer is:
used
'second-hand' is the definition.
(I've seen this in another clue)
'american name' is the wordplay.
'american' becomes 'us' (abbreviation for United States).
'name' becomes 'Ed' (short for Edward).
'us'+'ed'='USED'
'for' acts as a link.
(Other definitions for used that I've seen before include "not got directly" , "Sued (anag.)" , "Not fresh" , "Was treating" , "with some traffic" .)
