The phrase “by my troth” is an archaic expression that means “by my word” or “by my honor.” The term “troth” refers to faithfulness, loyalty, or truthfulness. In historical contexts, it was often used to affirm one’s promise or commitment, similar to saying “I swear” or “I promise.” This phrase can be found in literature, especially in works from the Middle Ages and the Renaissance, where characters might invoke their troth to emphasize their sincerity or fidelity to a pledge or relationship.
For example, in Shakespeare’s plays, characters might use such expressions to demonstrate their commitment to love or loyalty. Overall, it conveys a sense of earnestness and dedication in one’s words or promises.
