Star Trek often lifted names from other languages. Xindi is the name of a Chinese Township and a Chinese flute.
DS9's Jem'Hadar could be adapted from Jemadar, in (Middle-Far Eastern) feudal times referring to a ranking soldier battling commoners on his lord's territories. It was also used as a rank in the British Indian Army.
And Ferengi is from the Turkish and Arabic (or maybe Persian?) words for a European (derived from "Frank," i.e. a French person).
