The Saint strangely indecisive (8)
I believe the answer is:
hesitant
'indecisive' is the definition.
(synonyms)
'the saint strangely' is the wordplay.
'strangely' is an anagram indicator.
'the'+'saint'='thesaint'
'thesaint' is an anagram of 'HESITANT'.
(Other definitions for hesitant that I've seen before include "Indecisive" , "Slow to speak or act" , "Pausing - undecided" , "Doubtful" , "Uncertain, nervous" .)
