Chelovek — lyudi, rebyonok — deti: plurals that swap the root

The two most needed words about people swap their root entirely. Chelovek in the plural is lyudi: lyudey, lyudyam, s lyudmi. The form cheloveki does not exist — it marks a stranger the moment it sounds. For example: “На площади много людей, а детей меньше” — Many people are on the square, and fewer children. A rule from the Russian course: worked out on examples, not memorized as a wording.

How it works

The two most needed words about people swap their root entirely. Chelovek in the plural is lyudi: lyudey, lyudyam, s lyudmi. The form cheloveki does not exist — it marks a stranger the moment it sounds.

Rebyonok gives deti — a swap again: detey, detyam, s detmi. Yet rebyonki is possible — tenderly, about very small ones.

Collective words — narod, obshchestvo, bolshinstvo — stand in the singular: bolshinstvo prishlo, narod reshil. Living speech also says bolshinstvo prishli; talk forgives it, writing follows the rule.

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.
