polynya

Definition

A naturally formed transient area of open water surrounded by sea ice, especially in polar or subpolar seas.

Etymology

Borrowed from Russian полынья́ (polynʹjá, “polynya”) in the 1850s, from Middle Russian полыньѧ (polynʹja) (att. in 1639), from полыи (polyi, “open from above, uncovered; hollow”), whence also Russian полый (polyj, “hollow”), from Old East Slavic полъ (polŭ, “uncovered”), ultimately from Proto-Indo-European *pleh₂- (“flat”). The rare plural form polynyi is borrowed from Russian полыньи́ (polynʹí).
