One-way ticket left out for char (5)
I believe the answer is:
singe
'char' is the definition.
(thesaurus)
'one-way ticket left out' is the wordplay.
'one-way ticket' becomes 'single' (I've seen this before).
'left' becomes 'l' (common abbreviation).
'out' suggests deleting specific letters.
'single' with 'l' taken away is 'SINGE'.
'for' is the link.
(Other definitions for singe that I've seen before include "Earnest entreaty" , "Superficial burn" , "Burn; ignes (anag.)" , "Lightly burn" , "Scorch lightly" .)
