Unusually furtive Minoan giving little away (13)
I believe the answer is:
uninformative
'little away' is the definition.
I can't judge whether this definition defines the answer.
'unusually furtive minoan' is the wordplay.
'unusually' is an anagram indicator.
'furtive'+'minoan'='furtiveminoan'
'furtiveminoan' with letters rearranged gives 'UNINFORMATIVE'.
'giving' is the link.
Can you help me to learn more?
(Other definitions for uninformative that I've seen before include "far from enlightening" , "teaching nothing at all" , "of little use to student?" , "Revealing little" , "Providing no useful knowledge" .)
