Some faculty men have; call it insight (6)
I believe the answer is:
acumen
'insight' is the definition.
(I've seen this before)
'some faculty men have call' is the wordplay.
'some' means to look at the middle letters.
'faculty' becomes 'flair' (both can mean talent).
'have' indicates putting letters inside.
'call' becomes 'cu' (I can't justify this - if you can you should give a lot more credence to this answer).
The middle letter of 'flair' is 'a'.
'a'+'men'='amen'
'amen' placed around 'cu' is 'ACUMEN'.
'it' is the link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for acumen that I've seen before include "Shrewdness, intelligence in business" , "Shrewdness, sharpness of mind" , "intuition" , "Mental sharpness as in business" , "ingenuity" .)
