skerry

kari A small rocky island which may be covered by the sea at high tide or during storms.
1805, George Barry, History of the Orkney Islands, I:

The Seal (phoca vitulina, Lin. Syft.) which is here generally known by the name of selchy, is very common on most of our low shores, but particularly on those of the small holms and remote skerries, where it is frequently seen reposing and basking in the sun ....

Grim the Halogalander's crew sailed along Borgarfjord beyond the skerries, then cast anchor until the storm died down and the weather brightened up.

The three men proceeded, with a little difficulty, to scale the skerry, finding Gannets and Guillemots on the upper reaches.

Tae the icy flowes o the Shetlan voes he sailed tae Scalloway, / There his sweethairt won, far a Viking sun shines ower the skerries grey.
