What does vernix mean?
Vernix is a noun denoting a varnish-like or resinous coating. Its best-known modern use is for the soft, waxy substance that covers parts of a newborn's skin at birth; this material is commonly called vernix caseosa and can vary considerably in amount and appearance. Vernix can also refer more generally to a natural resinous coating produced by plants, particularly on young leaves and other growing surfaces. The word is uncommon outside medical, botanical, and specialist contexts. Although it overlaps in meaning with varnish, vernix tends to emphasize a natural or protective coating, while varnish commonly refers to a formulated liquid applied to objects. In this sense, the word also evokes the protective function of a thin layer that shields a delicate surface from drying, friction, or environmental exposure.

Much of the vernix on a newborn's skin is the very material that helped protect the skin while it was developing in the womb.
