Rosemary piece (5)
I believe the answer is:
sprig
'rosemary piece' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sprig that I've seen before include "Younger member of family" , "A child" , "Small leafy stem" , "Stem or spray" , "Grips with a small branch" .)
