English

Two aspects: doing and done

Almost every verb comes as a pair: one half for the process, one for the result. delat — to be doing; sdelat — to get it done. The language splits doing and done every single time: one verb for the course of things, one for the outcome. For example: “Я потерялся. Где я?” — I got lost. Where am I? A rule from the Russian course: worked out on examples, not memorized as a wording.

How it works

Almost every verb comes as a pair: one half for the process, one for the result. delat — to be doing; sdelat — to get it done. The language splits doing and done every single time: one verb for the course of things, one for the outcome.

You see it plainly in poteryatsya: ya poteryalsya — got lost and that is that, no process, no story of how it happened. The present of the done half points to the future: ya sdelayu — I will get it done.

Pairs are built with prefixes and suffixes: delat → sdelat, pisat → napisat, chitat → prochitat. Which pair a verb takes is a fact of the dictionary, not of grammar.

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.
