こと (koto)

Meaning & usage

ことだ gives firm advice and means should or ought to. It is used to tell someone the right action to take for health, study, or daily habits. It attaches to the dictionary form of a verb, as in 休むことだ or 飲むことだ. The tone is direct and instructive, so it suits advice from a teacher, doctor, or parent rather than polite requests to a superior.
