Skerry

A skerry is a small rocky island, usually defined to be too small for human habitation; it may simply be a rocky reef. A skerry can also be called a low sea stack.

The term skerry is derived from the Old Norse sker, which means a rock in the sea. The Old Norse term sker was brought into the English language via the Scots language word spelled skerrie or skerry. It is a cognate of the Scandinavian languages' words for skerry – Icelandic, Faroese: sker, Danish: skær, Swedish: skär, Norwegian: skjær / skjer, found also in German: Schäre, Finnish: kari, Estonian: skäär, Latvian: šēra, Lithuanian: Šcheras and Russian: шхеры (shkhery). In Scottish Gaelic, it appears as sgeir, e.g. Sula Sgeir, in Irish as sceir, in Welsh as sgeri, and in Manx as skeyr.

Skerries are most commonly formed at the outlet of fjords where submerged glacially formed valleys at right angles to the coast join with other cross valleys in a complex array. In some places near the seaward margins of fjorded areas, the ice-scoured channels are so numerous and varied in direction that the rocky coast is divided into thousands of island blocks, some large and mountainous while others are merely rocky points or rock reefs that menace navigation.
