Locative: Where?

The locative answers where? and about what? It always comes after a preposition: у (in), на (on, at), о (about) or по (around, across).

• Masculine and neuter nouns take -у: Београд → у Београду, сто → на столу, село → на селу, посао → на послу.
• Feminine nouns in -а take -и: соба → у соби, кухиња → у кухињи.
• Before this -и, к, г, х turn into ц, з, с: банка → у банци, књига → о књизи, рука → у руци.
• The neuter време becomes времену.

With у and на, the locative says where something is, not where it is going: Живим у Београду. (I live in Belgrade.) With по it means moving around inside a place: Шетамо по граду. (We walk around town.)
