# lighthouse

noun (lighthouse, lighthouses)

«lighthouse» in the English dictionary: everyday — its meanings, how the lessons use it, and examples, each with its tree on Mova.

## Everyday

A lighthouse is a tall tower by the sea with a bright light at the top that flashes to guide ships at night and warn them of rocks. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/L/lighthouse/#m1)

### In the lessons

In maths: a place in a story; its height, steps or the time between flashes are counted; flashes «every 10 seconds» make a pattern in time. In history and science: each lighthouse has its own pattern of flashes so sailors know which one it is; a lighthouse keeper looked after the light. In stories: a lonely lighthouse on a rocky island. Phrases: lighthouse keeper, lighthouse beam, the lighthouse flashes.
