Tertuim Quid
Tertium quid refers to an unidentified third element that is in combination with two known ones. It is Latin for "third something" (literally, "third what") In the Christological debates of the fourth century, it was used to refer to the followers of Apollinaris who spoke of Christ as something neither human nor divine, but a mixture of the two in a mysterious and inseparable way, and therefore a "third thing". This concept is also referred to as the hypostatic union.
