the.com/sty
A pig's home and an eyelid's grudge share one tiny, swollen name.
means Either a muddy pen where pigs are kept, or a red, painful lump on the edge of your eyelid.
from The pig pen traces to Old English 'stig,' an enclosure; the eyelid bump comes from 'styan,' meaning to rise or swell, later mangled into 'sty.'
Two rootsPig sty and eye sty are unrelated words.
Medical nameThe eyelid version is a hordeolum, a blocked gland.
Stye tooSpelled 'stye' only for the eye, never the pig.
