From Middle English traunce, from Anglo-Norman transe (“fear of coming evil; passage from life to death”), from transir (“to be numb with fear; to die, pass on”), from Latin trānseō (“to cross over”).
The verb is derived from Middle English traunce, trauncen, trancen (“to move about (?); to prance (?); to trample the ground”) (whence modern English trounce with the same senses, which see for more). The noun is probably derived from the verb.
Commonly used with the verbs 'fall into', 'go into', or 'be in'.
