Where it's somewhat flipping rank (4)
I believe the answer is:
tier
'rank' is the definition.
(tier is a kind of rank)
'where it's somewhat flipping' is the wordplay.
'somewhat' says the answer is hidden in the clue.
'flipping' is a reversal indicator.
'reit' is hidden in the letters of 'where its'.
'reit' back-to-front is 'TIER'.
(Other definitions for tier that I've seen before include "One making knot - level" , "band" , "Wedding cake feature" , "this person secures" , "He might do sailor's knots" .)
