Kotoryy: the word that bends by itself

Kotoryy takes its gender from the thing: kniga — kotoraya, uchebnik — kotoryy, pismo — kotoroe. You agree with it, not it with you. For example: “Это книга, которую я тебе советовал” — This is the book I recommended to you. A rule from the Russian course: worked out on examples, not memorized as a wording.

How it works

Kotoryy takes its gender from the thing: kniga — kotoraya, uchebnik — kotoryy, pismo — kotoroe. You agree with it, not it with you.

Then it bends by the role in the sentence. Drug, kotorogo ya zhdal — the one I was waiting for. Drug, kotoromu ya pozvonil — the one I phoned. Drug, o kotorom ya rasskazal — the one I spoke about. The questions whom? to whom? about whom? hand you the form.

Before kotoryy the writing puts a comma: Eto uchitel, kotoryy vedyot istoriyu. In speech a plain chto often does the job — film, chto vse khvalyat — people say it, but writing expects kotoryy.

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.
