Wechselpräposition

Etymology
From 🇰🇲.

Noun

 * 1)  A preposition that can be construed with more than one grammatical case, with the sense depending on this choice of case.

Usage notes

 * With regard to German grammar, the alternation is always between dative and accusative. The basic rule for this alternation is very straightforward: Dative is used when the preposition describes a stationary position or movement within a confined space. Accusative is used when the preposition describes movement from A to B.


 * However, the choice is often less intuitive in figurative use or in combination with certain verbs. For example, you say, but.
