locative case

Wiktionary

1. n. grammar A case used to indicate place, or the place where, or wherein. It corresponds roughly to the English prepositions "in", "on", "at", and "by". Languages that use the locative case include Armenian, Azeri, Belarusian, Catalan, Serbo-Croatian, Czech, Dyirbal, Latvian, Lithuanian, Polish, Quechua, Russian, Sanskrit, Serbo-Croatian, Slovak, Slovene, Swahili, Turkish and Ukrainian. Some languages use the same locative case construct to indicate when, so the english phrase "in summer" would use the locative case construct.
