The Nausicaan language was the language used by Nausicaans.
- Guramba - gumption, nerve, gall, etc.; as in: "Coward, like all Starfleet you talk and you talk, but you have no guramba."
- Undari - Used to describe cowards.
- "Orcho lok resnik Starfleet..." - Expressing amusement (to others) at the sight of Starfleet officers fighting each other. (TNG: "Tapestry")
In the Star Trek: Titan novel "Fortune of War", a character encounters written Nausicaan characters from the species' dominant language on a crashed alien starship.
