Oocyte

/ˈoʊəsaɪt/noun

An immature egg cell in the ovary, which becomes an ovum after it completes division.

The Greek roots

ᾠόν
ōión
egg
+
κύτος
kýtos
hollow vessel

Literally: egg vessel

The story of the word

κύτος meant a hollow jar or hull, and nineteenth-century biology drafted it as the standard ending for cell: leukocyte, erythrocyte, cytoplasm, all of them containers. A human female is born with every oocyte she will ever have, arrested mid-division, some of them waiting fifty years to finish. Latin ovum and Greek ᾠόν are cousins, which is why English ended up with both ovary and oocyte.
