Confined an enormous bird inside small bottle (9)
I believe the answer is:
parochial
'confined' is the definition.
(thesaurus)
'an enormous bird inside small bottle' is the wordplay.
'an' becomes 'a'.
'enormous bird' becomes 'roc' (mythical giant bird).
'inside' is an insertion indicator.
'small bottle' becomes 'phial' (a phial or vial is a small bottle).
'a'+'roc'='aroc'
'aroc' placed inside 'phial' is 'PAROCHIAL'.
(Other definitions for parochial that I've seen before include "Narrow in outlook" , "rather restricted" , "Having a narrow scope" , "Related to local area - narrow" .)
