noun
loch
LAHK/lɑːk/
A lake, especially in Scotland.
A narrow trail follows the shore of the quiet loch.

Etymology
Gaelic loch includes both lakes and lake-like bodies of water. Its application to narrow, nearly landlocked sea arms explains why a Scottish loch need not be an inland lake.
In context
sort of underwater radar. We built a flatpack sonar search vessel on a beach in 1981, patrolled up and down the loch.
