Midget
Midget (from midge, a tiny biting insect) is a term for a person of unusually short stature that is considered by some to be pejorative due to its etymology. While not a medical term like dwarf (for a person with dwarfism, a medical condition with a number of causes, most often achondroplasia), midget long described anyone, or indeed any animal, exhibiting proportionate dwarfism.
