(on the ground), militia becomes militiae (in military service, in the field), and focus becomes focī (at the hearth; at the center of the community). The first declension locative is by far the most common, because so many Roman place names were first declension, such as Roma, Rome, and therefore use the same form as the genitive and dative: Romae, at Rome, and Hiberniae, in Ireland. A few place-names were inherently plural, even though they are a single city, e.g. Athēnae, Athens and Cūmae, Cuma. These plural names also use the form similar to the dative and ablative: Athēnīs, at Athens, and Cūmīs, at Cumae. There are also a number of second declension names that could have locatives, e.g. Brundisium, Brindisi; Eborācum, York; with locatives Brundisiī, at Brindisi; Eborācī, at York. The locative cannot express being located at multiple locations; plural forms only exist because certain proper names such as Athēnae happen to be plural. "He is at home" can be expressed by "(is) domi est" using the locative, but "They are at their (individual and separate) homes" cannot be expressed by the locative. Greek In Ancient Greek, the locative merged with the Proto-Indo-European dative, so that the Greek dative represents the Proto-Indo-European dative, instrumental, and locative. The dative with the preposition ἐν en "in" and the dative of time (e.g., τῇ τρίτῃ ἡμέρᾳ (tēî trítēi hēmérāi), which means "on the third day") are examples of locative datives. Some early texts, in particular Homer, retain the locative in some words (for example ἠῶθεν (ēôthen) – at dawn, Iliad 24.401). Germanic languages The locative case had merged with the dative in early Germanic times and was no longer distinct in Proto-Germanic or in any of its descendants. The dative, however, contrasts with the accusative case, which is used to indicate motion toward a place (it has an allative meaning). The difference in meaning between dative and accusative exists in all of the old Germanic languages and survives in all Germanic languages that retain a distinction between the two cases. Sanskrit The locative case in Sanskrit is usually known as the "seventh case" (saptami vibhakti). It is the last out of the main seven cases (vibkhatis) in the language. Along with "in","on", "at", "or", and "by", the locative case is also generally used with "among" in Sanskrit. Slavic languages Among Slavic languages, the locative is mostly used after a fixed set of
