Very LowTechnical/Scientific
Definition
Meaning
A named surface feature (a dark region) on the planet Mars; a specific 'sea' in the Martian nomenclature.
A historical and geographical term in planetary science referring to a large, dark basaltic plain on Mars, located in its southern highlands. The name is Latin, meaning 'Cimmerian Sea', and reflects the earlier telescopic view of Martian features as resembling seas.
Linguistics
Semantic Notes
The term is a proper noun in Martian planetary nomenclature. It is capitalized. The concept of a 'mare' (Latin for 'sea') on Mars is an antiquated telescopic perception; these features are now known to be volcanic plains, but the traditional names remain.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing 'mare' (Latin: sea) with the English word 'mare' (female horse).
- The term is a direct Latin borrowing, not a descriptive English phrase, so it should not be translated word-for-word into Russian in technical contexts.
Common Mistakes
- Incorrectly writing it as 'mare cimerium' or 'mary cimmerium'.
- Using lowercase ('mare cimmerium') in formal scientific writing.
- Mispronouncing 'cimmerium' with a hard 'c' (/k/); it is soft (/s/).
