"Didst one's bit" is an archaic phrase that dates back to Early Modern English, specifically the period of Middle English to Modern English transition. The term "didst" is the second person singular past tense of the verb "do," meaning "to perform" or "to carry out." "One's" refers to an unspecified individual, representing the subject of the verb "do," and "bit" signifies a small portion or contribution.
When used together in the phrase "didst one's bit," it implies that someone has fulfilled their duties, responsibilities, or obligations. It conveys the idea of doing one's fair share or contributing to a collective effort. The phrase emphasizes personal involvement and effort, suggesting that an individual has taken part in a particular task, activity, or project.
The usage of "didst one's bit" often implies a sense of patriotism, solidarity, or loyalty. It is commonly associated with times of war, where individuals are encouraged or compelled to actively contribute to their community or country's defense. It suggests that each person has done their part in supporting a larger cause, be it military or otherwise.
However, due to its archaic nature, the phrase is rarely used in contemporary English. It is mainly encountered in historical literature, particularly works from the Renaissance era and earlier.
