The proper spelling of "doeth one duty" is dʌð wʌn ˈdjuːti. In this phrase, "doeth" is the archaic third-person singular present tense of the verb "do," and "duty" refers to one's responsibility or obligation. The use of "doeth" is rare in modern English, and it is usually replaced with "does."

The phrase "doeth one duty" can be better understood by breaking it down into its constituent terms. The term "doeth" is an archaic form of the verb "do," used in the third person singular present tense. The verb "do" encompasses a wide range of actions and activities. It denotes performing, executing, or carrying out a task, responsibility, or obligation. Thus, "doeth" signifies the act of accomplishing or fulfilling something.
