Fractions of a yard (4)
I believe the answer is:
feet
'fractions of a yard' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for feet that I've seen before include "Have both on the ground to be practical" , "Measures - body parts" , "Paws" , "Three of these in yard" , "On which we stand" .)
