noun
cove
KOHV/kəʊv/
A small sheltered bay or coastal inlet.
The rocky headlands shelter a calm cove from the rougher sea.

Etymology
The image is of a small chamber or hollow nook. The coastal meaning apparently developed through a Scottish sense, “small hollow place in coastal rocks,” extending the enclosed-space image to an inlet.
In context
the three girls, carrying a tea basket and several parcels, were walking along the cliffs above the cove.
