Trill Name Generator

Trill names in Star Trek carry a rule no other Federation species has: when a Trill is joined, they drop their family name and take the name of the symbiont. Ezri Tigan became Ezri Dax the moment the Dax symbiont was implanted, joining a line that already included Lela, Tobin, Emony, Audrid, Torias, Joran, Curzon and Jadzia. Unjoined Trill keep ordinary family names such as Tigan, so a Trill character's surname tells you immediately whether they carry a symbiont.

Personal names are short and soft, usually two syllables with open vowels: Jadzia, Ezri, Curzon, Lenara, Adira, Gray, Senna, Verad. Symbiont names are even shorter, typically one or two syllables ending in a consonant: Dax, Kahn, Odan, Tal, Kalon, Landi. That contrast, a flowing given name and a clipped symbiont name, is the sound of a Trill name. Titles like Guardian (for the caretakers of the symbiont pools) and roles from the Symbiosis Commission can stand in for names among the unjoined.

For an original Trill, invent a symbiont name first, since it will outlive any single host, then give each host in its line a distinct personal name. The list here includes canon hosts and symbionts from Deep Space Nine, The Next Generation and Discovery, plus original joined and unjoined Trill built to the same pattern.
