Learn Russian.One sentence at a time.
Read a text. Save the word you need. Write your own thoughts.
Cyrillic looks intimidating for a week. Six cases look intimidating for a month. Then you start reading and both quietly resolve themselves. Lex is built for that quiet, steady kind of learning.

01WHY THIS PAIR
Russian grammar,learned by reading it in context.
Six cases. Verbs in aspectual pairs. Word order that shifts to shift emphasis. Russian is the kind of grammar you understand by seeing it repeat across dozens of real sentences — not by memorising a wall of endings. Lex is built for that.

A morning in my neighborhood
Вчера утром я пошёл в кафе рядом с домом. Было ещё рано, и на улице было тихо. Я заказал кофе и булочку. Продавщица рассказала мне о районе.
У окна я познакомился с новый сосед. Он живёт в моём доме уже несколько месяцев. Рассказал, где по воскресеньям работает маленькая булочная. Я вернусь на следующей неделе.

BEFORE YOU START
A few good questions.
It helps, but you don't need to be fluent — most learners pick up the alphabet in a week or two. A1 texts stick to short sentences with a lot of repetition, which is exactly what your eyes need to make Cyrillic feel automatic.
