Derived from the Latin hordeolus (hordeum meaning "barley” and ulus meaning it has the appearance of), this infection—which results in a lump that might resemble an individual grain of barley—occurs when bacteria get into an oil or sweat gland in the eyelid.
Horripilation comes from the Latin horrere (“to stand on end”) and pilus (“hair”), and the phenomenon occurs when the tiny muscles at the bottom of hair follicles contract. In furry mammals, this causes hairs to “stand on end,” making the animal appear larger to scare off predators. In humans, it is a “vestigial reflex” (it no longer serves a purpose) and instead just makes skin look temporarily bumpy and rough.
From the Latin lens (lentils), lentigines are flat, well-defined skin discolorations that can grow to an inch in diameter, sometimes combining with other spots so they look even larger. Age spots are harmless, though they make skin look older.
From the Norwegian word kveis (“discomfort following overindulgence”), this is your body’s response to the breakdown products of alcohol, with symptoms such as headache, dry mouth, nausea, muscle aches, and dizziness.
