SUMMARY
The terms "orthonormal tetrad" and "orthonormal frame" refer to the same mathematical concept, although the use of "tetrad" is technically limited to four-dimensional contexts. The prefix "tetr-" originates from Greek, meaning "four," which clarifies its specific application. This distinction is crucial for accurate communication in fields such as relativity and field theory.
