What is the Latin or greek root of word training?

The word "training" doesn't have a direct Latin or Greek root. It comes from the Old English word "trān" meaning "to draw, drag, or pull." This word is related to the Old Norse word "traina," meaning "to draw."

The concept of "training" as we know it today developed later, but the origin of the word reflects the idea of guiding, shaping, or pulling something towards a specific goal, which is still relevant to its modern meaning.
