Liable to error, bail fell out! (8)

Ross

I believe the answer is:

fallible

'liable to error' is the definition.
(thesaurus)

'bail fell out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'bail'+'fell'='bailfell'
'bailfell' with letters rearranged gives 'FALLIBLE'.

(Other definitions for fallible that I've seen before include "Capable of erring" , "Northern Scandinavian" , "Likely to fail or make errors" , "errant, possibly" , "Capable of making mistakes" .)

I've seen this clue in The Times.
