Definition
In German, “application” is Bewerbung and can be used for jobs, internships, scholarships, shared flats, and even marriage proposals! The verb is sich bewerben.
Note: The preposition when applying FOR something is typically um, though many people also use auf and, incorrectly, für. When applying AT a place, it’s bei.
