Crossword Genius

Some jaw the most, column disclosed (7)

Ross

I believe the answer is:

maxilla

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

'some jaw' is the definition.
(thesaurus)

'most column disclosed' is the wordplay.
I cannot really see how this works, but
'most' could be 'max' (maximum) and 'max' is found within the answer.
This may be the basis of the clue (or it may be nonsense).

'the' is the link.

Can you help me to learn more?

(Another definition for maxilla that I've seen is " Jawbone".)

I've seen this clue in the Sydney Morning Herald.
