Though consulted, may make nothing clear (6)

I believe the answer is:

oracle

I'm a little stuck... Click here to teach me more about this clue!

'though consulted may' is the definition.
I can't judge whether this definition defines the answer.

'make nothing clear' is the wordplay.
'make' is an anagram indicator.
'nothing' becomes 'o' (looks like zero - 0).
'o'+'clear'='oclear'
'oclear' with letters rearranged gives 'ORACLE'.

Can you help me to learn more?

(Other definitions for oracle that I've seen before include "Seer" , "Shrine; its message" , "Bringer of divine revelation" , "Prophetic priest/priestess" , "(Prophecy given at) shrine" .)

I've seen this clue in the Evening Standard.
