Stress: one letter decides the word

Stress is not written, yet it makes the word: zAmok, stress early, is a fortress; zamOk, stress late, is the thing on a door. mUka is torment, mukA is flour. Same letters — two different words. For example: “Это новый замОк, а вон зАмок” — This is a new lock (on the door), and over there a fortress. A rule from the Russian course: worked out on examples, not memorized as a wording.

How it works

Stress is not written, yet it makes the word: zAmok, stress early, is a fortress; zamOk, stress late, is the thing on a door. mUka is torment, mukA is flour. Same letters — two different words.

An unstressed o shrinks toward a: moloko sounds like malako, and the spelling hides it. For the first weeks, check the stress of each new word — the examples mark it.

Stress also jumps between forms: ruka, but rUki; god, but godY. No rule produces it: the pair of forms is learned together with the word.

By example

  • Это новый замОк, а вон зАмок
    Eto novyy zamOk, a von zAmok
    This is a new lock (on the door), and over there a fortress
  • Молоко, мука и дорога — везде «а» вместо безударного «о»
    Moloko, muka i doroga — vezde «a» vmesto bezudarnogo «o»
    Milk, flour and road — an a sounds wherever the o is unstressed
  • Одна рука, две руки
    Odna ruka, dve ruki
    One hand, two hands

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.
