Senpai and kōhai
In plain English
A relational pair ordered, in schools and workplaces, by when each person entered the institution. The word literally means “one born earlier”, and the standard dictionaries also record a broader sense covering age, position and experience — but in institutional use it is entry order that decides. It carries expectations of guidance in one direction and deference in the other, and is marked in speech.
Literally
Earlier colleague and later colleague.
Commonly mistaken for
Not equivalent to boss and subordinate, and not primarily about age. Someone older can be your kōhai if they joined later, which is why the pair is best understood as entry-order seniority.
