Resort area discovered on voyage (8)
I believe the answer is:
recourse
'resort' is the definition.
(synonyms)
'area discovered on voyage' is the wordplay.
'discovered' means to look at the middle letters.
'on' says to put letters next to each other.
'voyage' becomes 'course' (both can mean a route or journey).
The central letters of 'area' are 're'.
're'+'course'='RECOURSE'
(Other definitions for recourse that I've seen before include "Resource as a means of help" , "one looked to for help?" , "One resorted to" , "A source of help in a difficult situation" , "Expedient" .)
