Binnacle (noun)

A housing or case for a ship's compass, typically located on the deck and having a chart table, shelves for books and instruments, and a lamp.

Origin:

Late 17th century: probably from portuguese binnacle, denoting a beacon or lighthouse, from latin binaculum 'crane, scaffold,' from bini 'in twos,' because two were used for a beacon.

Examples:

1. The binnacle was an important part of a ship's navigation equipment.
2. The binnacle was designed to protect the ship's compass from the elements.
3. The captain consulted the binnacle frequently to ensure that the ship was on course.
4. The binnacle was lit at night, making it easier for the navigator to use the compass.
5. The binnacle was an essential component of a ship's infrastructure, without which safe navigation would have been impossible.
