Our Clara turns out to be prophetic (8)
I believe the answer is:
oracular
'prophetic' is the definition.
(similar in meaning)
'our clara turns out' is the wordplay.
'turns out' is an anagram indicator.
'our'+'clara'='ourclara'
'ourclara' anagrammed gives 'ORACULAR'.
'to be' is the link.
(Other definitions for oracular that I've seen before include "In the manner of one possessing divine wisdom" , "To do with advice or prophecy as from ancient Greeks" , "Spoken in the manner of divine announcements" , "Wise and prophetic" , "Auspicious" .)
