Another name for a return voyage (5)
I believe the answer is:
alias
'another name' is the definition.
(I've seen this in another clue)
'a return voyage' is the wordplay.
'return' shows that the letters should be reversed in order.
'voyage' becomes 'sail' (sail is a kind of voyage).
'sail' in reverse letter order is 'lias'.
'a'+'lias'='ALIAS'
'for' is the link.
(Other definitions for alias that I've seen before include "Assumed identity" , "Otherwise - an assumed name" , "Cabbage salad" , "Alternative name" , "aka" .)
