Where I am: the at-form after u and na
One and the same preposition, u, answers both "where to" and "where at" — the ending tells them apart. Idem u apoteku (to the pharmacy — motion) and Ja sam u apoteci (at the pharmacy — location). English splits them as "to the pharmacy" vs "at the pharmacy"; Serbian keeps u and bends the noun instead. For example: “Лек се купује у апотеци” — Medicine is bought at the pharmacy. A rule from the Serbian course: worked…
How it works
One and the same preposition, u, answers both "where to" and "where at" — the ending tells them apart. Idem u apoteku (to the pharmacy — motion) and Ja sam u apoteci (at the pharmacy — location). English splits them as "to the pharmacy" vs "at the pharmacy"; Serbian keeps u and bends the noun instead.
The at-form ending is simple: -u for masculine and neuter (na stolu, u gradu, na spratu), -i for feminine (u sobi, u školi, u bolnici).
And then comes the twist English never makes. If a feminine word ends in k, g, h, those consonants soften before the -i: k → c, g → z, h → s. ruka → u ruci, noga → na nozi, apoteka → u apoteci, banka → u banci — exactly the reshuffle English does in "critic → criticise". Hearing u banci, do not hunt for a new word: it is still the bank.
The preposition na works the same way, and choosing between u and na is plain vocabulary: u gradu but na pijaci; u stanu but na spratu. Memorize the pairs with the nouns.

How the rule settles in your head
A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
