Guy coming into Algarve resort brings hash (7)
I believe the answer is:
farrago
'hash' is the definition.
(I've seen this before)
'guy coming into algarve resort' is the wordplay.
'guy' becomes 'rag' (both can mean to tease or mock).
'coming into' is an insertion indicator.
'algarve resort' becomes 'Faro' (Faro is a city in the Algarve).
'rag' going into 'faro' is 'FARRAGO'.
'brings' is the link.
(Other definitions for farrago that I've seen before include "Confusion" , "A hotchpotch, perhaps of nonsense" , "Hotchpotch or jumble, as of nonsense" , "Motley assortment of things" , "Confused mass" .)
