## Definition

dark or gloomy. It is an old word that people used to describe a place that was hard to see in.

For teachers: characterised by darkness, gloom, or obscurity. Primarily found in historical or dialectal contexts; the modern equivalent is 'murky'.

## Examples

- The forest grew merck as the sun went down.
- The travelers struggled to find their way through the merck corridors of the ancient castle.
- In the merck depths of the cavern, the flickering torchlight barely revealed the jagged edges of the limestone walls.

## Pitfalls

- Not "The water was very merck." but "The water was very murky." — Learners should use the modern word 'murky' instead of the archaic 'merck' in contemporary speech.

## Usage notes

- Typically used as a predicative or attributive adjective in literary or archaic contexts.
