Midget (5)
I believe the answer is:
dwarf
'midget' is the definition.
(I know that midget can be written as dwarf)
This is the entire clue.
(Other definitions for dwarf that I've seen before include "No. of minutes in degree" , "Doc? Grumpy?" , "Sleepy, perhaps" , "Diminutive person or thing" , "Stunt the growth of" .)
