lacus
[ˈɫa.kʊs]masculine
The Latin word for lake is lacus.
The term lacus refers to a body of water.
Meaning: body of water (noun)
Which one should you use?
While lacus is the general term for a lake, Stagnum is used to refer specifically to a standing or stagnant body of water. If the body of water is a marsh, a swamp or a particularly small and shallow lake, the word Palus is more appropriate.
How does it change in a sentence?
The word lacus is the nominative singular form, which you use when the lake is the subject of a sentence. If the lake is the direct object of a verb, such as in the phrase 'I see the lake', the form changes to lacum.
Did you know?
- The Latin lacus can be used metaphorically in poetry to describe a 'lake' of blood or tears.
- The English word 'lacustrine', used in geology to describe things related to lakes, is derived directly from lacus.
- Even though 'lake' and lacus sound similar, the English word 'lake' is actually a closer relative to the Old English word 'lagu', which meant 'sea' or 'ocean' rather than a small body of water.
