Usage notes

 * Whenever a preposition stands immediately before any of the oblique cases of the third-person pronoun (singular or plural) and directly governs it, then an must be prefixed to the pronoun: ; ; ; ;.
 * This comes from Proto-Slavic prepositions such as (compare  and ), that originally ended in  and governed oblique cases. Since the prepositions and the pronouns occurred together so often, it was easy to lose track of which word the final  belonged to, and so it was reinterpreted as part of the pronouns; compare, which was reinterpreted in the same way. Proto-Slavic   became modern Russian , and this rule was extended to all prepositions governing any third-person pronoun.
 * Note that if the preposition does not directly govern (i.e. when  is a possessive pronoun), then  is not added: ; ;.
 * When there is another word separating a preposition and any oblique case of, then is not added:.
