What does stye mean?
A stye is a small, tender, red swelling on the edge or inside of an eyelid. It develops when one of the eyelid's oil glands becomes blocked and infected, most often with bacteria. The upper or lower eyelid may be affected, and the condition can make the eye look swollen and irritated, although the eye itself is not usually damaged. Most styes are minor and clear naturally, while warm compresses may ease discomfort. In medical writing, a stye is called a hordeolum. The word should not be confused with a chalazion, which is a persistent, generally noninfectious blockage of an eyelid gland. Although “stye” is most familiar in this modern medical sense, it also has an archaic verb meaning “to rise” or “ascend,” surviving mainly in older literary and poetic language.
An acute, painful, red swelling on the eyelid caused by infection of an oil gland.

A stye sounds like a pig's home, but both words descend from an old Germanic family associated with standing or rising.
