Degree of precision among Romanic etymologists (6)
I believe the answer is:
nicety
'degree of precision' is the definition.
(I've seen this before)
'among romanic etymologists' is the wordplay.
'among' indicates the answer is hidden within the clue.
'NICETY' is hidden in the letters of 'romanic etymologists'.
(Other definitions for nicety that I've seen before include "Matter of delicate adjustment" , "Fine distinction" , "Exactitude" , "Fine point or subtlety" , "Subtle difference" .)
