Troth (troth, trohth)

1. One’s pledged word, loyalty, or fidelity.

2. Truth.

3. Betrothal.

To pledge or betroth.

From Old English treowth (fidelity, truth), from treowe (faithful). Ultimately from the Indo-European root deru- (to be firm), which gave us truth, trust, tree, endure, druid, during, durable, duress, trow and indurate.
