Largest loch in Scotland by volume

NESS

Think of the deep, mysterious Scottish body of water often linked to a legendary creature.

The clue asks for the largest loch in Scotland by volume, which is Loch Ness—famous for its deep waters and the mythical "Loch Ness Monster." The answer is shortened to "NESS," a common crossword trick where the full name is clipped to its most recognizable part. Since "loch" is implied by the clue, only the distinctive second word is needed. This kind of abbreviation is standard in puzzles to keep answers concise.
