In Chichewa, Ruth shows enough deference by addressing Boaz as “my lord” (mbuye wanga ‘my master/uncle’), and she does not have to go on to refer to herself as “your maidservant” (which might well be interpreted literally in this context). This also eliminates any possible confusion with her subsequent words: ” . . . though I am not one of your maidservants.”
