Yes, but it is a made up definition.
Strong says this was applied both in the OT and the NT to teachings handed over, both written and orally. Strong notes that it is applied to Paul's and Moses' teachings too.
Depending on the accompanying adjective, it might be oral tradition, written tradition, Divine tradition, human tradition, Sacred Tradition, Apostolic Tradition, family tradition, etc.
OT Hebrew and NT Greek did not have capital letters, but in English, the choice of lower-case or upper-case T is occasionally used to distinguish between the generic "something handed down" ("This handwritten recipe is for Grandma's traditional Christmas cookies") and something sacred or authoritative (Christian Tradition defines the Three-personed Oneness of God, the Trinity.")
So these meaning has been around awhile.
