and meaning (jedná se o to ≠ jedná se o tom). If the preposition uses both accusative and locative case, the accusative is used for direction (where to) while locative for pure location (where). In case of the preposition "o" (about), this distinction can be very subtle and untranslatable, or depending on the controlling verb. The locative form of substantives in the singular is mostly identical with the dative case (3rd case). Possible endings for locative case: -u (hard masculines: o pánu, hradu, hard neuters: městu) -i (soft masculines: o muži, stroji, soudci, some neuters: moři, some feminines: růži, písni, kosti) -ovi (animate masculines: o pánovi, mužovi, předsedovi, soudcovi) -e (o lese, o Mařce) -ě (na hradě, o ženě, o městě) -eti (o kuřeti, knížeti) -í (o stavení) For adjectives and adjectival substantives: -ém (-ým or -ym in Common Czech) for hard masculine and neuter adjectives (o mladém, vo mladým, o vrátném) -m for soft masculine and neuter adjectives (o jarním, o průvodčím) -é (-ý or -ej in Common Czech) for hard feminine adjectives (o mladé, vo mladý, vo mladej) -í for soft feminine adjectives (o jarní) The locative form in the plural typically has the ending "-ch" (o mladých ženách), the dual has ending -ou (v obou dvou případech, na rukou). See Czech declension for declension patterns for all Czech grammatical cases, including the locative. Slovak The Slovak language uses the locative case to denote location (na Slovensku/in Slovakia), but as in the Russian language, the locative case may be used after certain prepositions with meanings other than location (o Bratislave/about Bratislava, po revolúcii/after the revolution). Cases other than the locative may be used to denote location in Slovak as well (U Milana/at Milan's house -genitive, or nad stolom/above the table -instrumental). A preposition must always be used with this case. There are several different locative endings in Slovak: -e Used for singular nouns of all genders (except masculine animate), e.g. stôl → o stole, láska → v láske, mesto → po meste. -u Used for: Masculine inanimate singular nouns ending in a velar consonant, e.g. hliník → o hliníku, mozog → v mozgu, bok → na boku, vzduch → vo vzduchu, or a glottal consonant, e.g. hloh → po hlohu All neuter singular nouns ending in -kV, -chV, -iV, -uV (V being o or um), e.g. jablko → v jablku, ucho → na uchu, akvárium → pri akváriu,
