T'hy'la 

A Vulcan word meaning "friend, brother, and/or lover". First used in the novelisation of Star Trek: The Motion Picture, the word was created by Gene Roddenberry to describe the relationship between Captain Kirk and Spock.

An excerpt from the novel says "Editor’s note: The human concept of friend is most nearly duplicated in Vulcan thought by the term t’hy’la, which can also mean brother and lover."

T'hy'la is popularly used in Kirk/Spock slash stories, where "soul-mate" and "life-long companion" are often accepted within fanon as additional definitions of T'hy'la.

Jim! Good-bye my . . . my t'hy'la. This is the last time I will permit myself to think of you or even your name again.
-- Spock's thoughts before almost undergoing Kolinahr, a Vulcan ritual to purge all emotion. (Star Trek: The Motion Picture novel, page 14-15.)

There was much to be put out of his mind. Why was it difficult to forget Chekov’s astonished delight which greeted him at the command airlock when he boarded? And on the bridge—Kirk! The mere name made Spock groan inwardly as he remembered what it had cost him to turn away from that welcome. T'hy'la!
-- (Star Trek: The Motion Picture novel, page 109.)

Thylacine

The most awesome marsupial to ever live. It had pouches on both sexes, five full toes on the front (no lame dew claw like dogs), and could jump just like a kangaroo! It had stripes on its back (from eleven to twenty one, typically). It was the best.

Sadly, when extinct in 1936 on the 7th of September due to the inaccessibility to shelter and the idiots at the Hobart Zoo.

-Hey, ma, looks, it's a Thylacine !
-No, Billy, that's just a kangaroo with but stripes.
