Usage notes
The accusative and prepositional forms are used only when кой is on its own (not in front of a noun) and refers to a person. In informal Bulgarian the nominative form is often used instead of the accusative and prepositional ones (Кой поканиха, с кой разговарям). This usage is not considered standard.

Pronoun

 * 1) Direct object form of .

Usage notes
The alternative form ко́го (with stress retraction onto the first syllable) is used after prepositions.
