Chto, potomu chto, esli, kogda: two thoughts in one sentence

Two short sentences are stitched with a conjunction: "We are celebrating at home. The whole family is together" becomes My prazdnuem doma, potomu chto vsya semya vmeste. A comma stands before the conjunction, always — even before a short chto. For example: “Я люблю Новый год, потому что вся семья вместе” — I love New Year because the whole family is together.

How it works

Two short sentences are stitched with a conjunction: "We are celebrating at home. The whole family is together" becomes My prazdnuem doma, potomu chto vsya semya vmeste. A comma stands before the conjunction, always — even before a short chto.

Word order inside the second half does not move: the verb stands where it would stand alone. Ya znayu, chto ty pridyosh zavtra — none of the reshuffling other languages do.

The conjunctions divide the work: chto retells someone's words, potomu chto gives the reason, esli builds a condition, kogda sets the time. The conclusion takes another word, poetomu: Ya boleyu, poetomu ostayus doma — no conjunction there, a consequence.

In speech the link is often trimmed: Ya znayu, chto pridyosh instead of chto ty pridyosh — an extra word falls out when the meaning is clear. In writing the comma and the order are required all the same.

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.

“Я люблю Новый год, потому что вся семья вместе” (Ya lyublyu Novyy god, potomu chto vsya semya vmeste) — I love New Year because the whole family is together. A rule is easier to test on sentences like this than to memorize as a wording: what surfaces in conversation is the sentence.
