Hands and feet (5)
I believe the answer is:
units
'hands and feet' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for units that I've seen before include "Eg, cm, kg and ft" , "Single parts of a whole" , "Single items or standard quantities" , "Single things" , "Individual things as parts of a whole" .)
