Try out is ruined with too many sighteers around (8)
I believe the answer is:
touristy
'too many sighteers around' is the definition.
I can't judge whether this defines the answer.
'try out is ruined' is the wordplay.
'ruined' is an anagram indicator.
'try'+'out'+'is'='tryoutis'
'tryoutis' with letters rearranged gives 'TOURISTY'.
'with' is the link.
Can you help me to learn more?
(Other definitions for touristy that I've seen before include "Full of sightseers" , "popular with holidaymakers" .)
