Fair way to share (6)
I believe the answer is:
evenly
'fair way to share' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for evenly that I've seen before include "Smoothly or fairly" , "In calm or level manner" , "Smoothly, uniformly" , "In smooth or level manner" , "Calmly or equitably" .)
