Old roan out in Floridian city (7)
I believe the answer is:
orlando
'floridian city' is the definition.
(I've seen this before)
'old roan out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'old'+'roan'='oldroan'
'oldroan' anagrammed gives 'ORLANDO'.
'in' is the link.
(Other definitions for orlando that I've seen before include "___ Gibbons, English composer of madrigals - Florida resort city" , "Bloom in film" , "place in Florida" , "Site of Walt Disney World" , "2016 Invictus Games city - Virginia Woolf novel" .)
