Tried fire out, scared (9)
I believe the answer is:
terrified
'scared' is the definition.
(terrifying is a kind of scaring)
'tried fire out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'tried'+'fire'='triedfire'
'triedfire' is an anagram of 'TERRIFIED'.
(Other definitions for terrified that I've seen before include "Panic-stricken - dire refit (anag)" , "Greatly frightened" , "Extremely frightened" , "Scared stiff" .)
