The accusative/dative prepositions have a frightful reputation for frustrating or intimidating students. A practical and simple solution is available, however, to teach students how to choose the proper case when confronted with an "either/or" preposition. The best place to start is with the preposition in, the most frequently employed of the accusative/dative prepositions, and the one clearest in meaning to English-speaking students.' Once students understand the underlying destination/location concept in the case of in, they can readily apply it to the other accusative/dative prepositions and the difficulties encountered in the less frequent applications will be more easily overcome.

At least one of the plural examples should not end in "n."
