In systemic functional linguistics, the term tenor refers to the participants in a discourse, their relationships to each other, and their purposes.
In examining how context affects language use, linguists refer to the context-specific variety of language as a register. The three aspects of the context are known as field, tenor and mode. Field refers the subject matter or content being discussed. Mode refers to the channel (such as writing, or video-conference) of the communication. By understanding these three variables, the kind of language likely to be used in a particular setting can be predicted — and, Michael Halliday suggests, this is exactly what we do, unconsciously, as language users.

The Aztec themselves, according to definite tribal tradition, reached the valley of Mexico from the far North, and linguistic evidence established their connection with the great Shoshonian linguistic stock whose tribes extend almost continuously along the backbone of the continent from the Columbia River to the Isthmus of Panama.
In the same way the Apache and Navajo of the Mexico border are known to have emigrated from the frozen shores of the Yukon and Mackenzie.
The only apparent exceptions to the general rule of decay are the Iroquois, Sioux, and Navaho, the first two of whom have kept up their number by wholesale adoptions, while the Navaho have been preserved by their isolation.
