This is a short, practical page about a single symbol you will see on almost every Russian word in this guide: the little slanted mark over a vowel, as in молоко́ ("milk") and хорошо́ ("well, good"). It is the stress mark, and understanding what it is — and, just as importantly, what it is not — will save you confusion from your very first lesson. The one-sentence version: the mark shows you which syllable to say loudest, this guide adds it to help you learn, and real Russian writing leaves it out entirely.
What the mark is
The mark is an acute accent (´), placed over the vowel of the stressed syllable — the syllable you pronounce with the most force and the clearest vowel. Russian words have exactly one stressed syllable, and the rest are weaker.
молоко́
milk — the mark over the last о tells you to stress that syllable: 'ma-la-KO.' The other two о's are unstressed and reduced.
хорошо́
well, good — stress on the final о: 'kha-ra-SHO.'
спаси́бо
thank you — stress on the middle и: 'spa-SEE-ba.'
That is the whole job of the mark: point at the loud syllable. But why does Russian need you to be told? Because, unlike many languages, Russian stress is unpredictable — you cannot work it out from the spelling. Two words spelled with the same vowels can be stressed differently, and getting the stress wrong cascades into getting the vowels wrong too (the unstressed ones change quality). That is why this guide marks it for you, and why word-stress-basics is the next page to read.
The crucial point: real Russian text has NO stress marks
Here is the thing every learner must absorb early. Native Russian books, newspapers, websites, signs, and text messages do not write stress marks at all. Russians simply know where the stress falls on each word, the way English speakers "just know" that record (the noun) and record (the verb) are stressed differently without anything in the spelling telling them.
So in the wild, молоко́ is written молоко — bare, no mark. The accent you see in this guide is a learning aid, added on purpose, and the same convention you will find in:
- dictionaries (every headword is marked),
- textbooks and graded readers for learners,
- children's first readers in Russia,
- this grammar guide.
молоко́ (here) → молоко (real text)
milk — marked in this guide to teach you the stress; written without the mark in everything an adult Russian reads.
Я люблю́ ко́фе с молоко́м. (here) → Я люблю кофе с молоком. (real text)
I like coffee with milk. — the same sentence as you'll see it here, and as it actually appears in Russian.
Two automatic cases: ё and single-syllable words
Two kinds of words are never marked, and for good reasons.
The letter ё is always stressed. Wherever ё appears, that syllable carries the stress — there is no such thing as an unstressed ё. So marking it would be redundant; the letter is its own stress mark.
ёлка
fir tree / Christmas tree — stress automatically on ё: 'YOL-ka.' No acute needed; ё is always the stressed syllable.
актёр
actor — the ё carries the stress: 'ak-TYOR.' You never need a mark on ё.
всё
everything / all — ё is stressed: 'fsyo.' (Note: in real text ё is itself often printed plain as е, which is a separate spelling issue — see the ё page.)
There is a wrinkle worth a heads-up: real Russian text often prints ё as plain е, dropping the two dots. That is a spelling habit, not a stress issue, and it is covered on the ё page. For your purposes here: when you do see ё, it is stressed, full stop.
Single-syllable words are never marked. A word with only one vowel has only one syllable, so there is nowhere else the stress could go. Marking it would tell you nothing.
дом
house — one syllable, so no mark: the stress can only fall here.
стол / кот / я / ты
table / cat / I / you — all single-syllable, all unmarked; there is only one place the stress can be.
Do NOT write the marks yourself
This is the practical instruction that trips people up. The marks are for reading and learning. When you write Russian — homework, messages, anything — write the bare letters, no accents. Adding stress marks to your own Russian is a tell-tale beginner habit; native text never has them, and putting them in looks the way it would look if an English learner wrote little stress dots over every English word.
✅ Я живу в Москве.
I live in Moscow. — how YOU should write it: no stress marks.
❌ Я живу́ в Москве́.
Same sentence with marks — fine for THIS GUIDE to teach you, but you should not write the marks yourself.
The division of labour is simple: read the marks to learn each word's stress; store the stress in your memory as part of the word; write without marks, like a native.
How to use the marks while you learn
Put it all together into a habit you can run from day one:
- See a new word. Note where the acute sits — that's the loud syllable.
- Say it with that syllable strong and let the unstressed vowels go weak (the reason they reduce is on vowel-reduction-akanye).
- Learn the stress as part of the word, not as a separate fact to add later.
- Write the word without the mark when it's your turn to produce it.
Because Russian stress can also move as a word changes form (e.g. across its case or tense forms), the mark is something you'll keep relying on as you meet each new form — that mobility is the subject of mobile-stress. For now, the marks in this guide are simply your reliable signpost to "say this syllable loudest."
Common Mistakes
❌ Writing молоко́ with the acute in your own homework
Incorrect — stress marks are a learning aid; native text and your own writing should be bare: молоко.
✅ Read молоко́ here, write молоко yourself
milk — learn the stress from the mark, but don't reproduce the mark.
❌ Putting a stress mark on ё (e.g. ё́лка)
Incorrect — ё is always stressed, so it is never marked; the letter already signals the stress.
✅ ёлка
fir tree — ё carries the stress automatically; no acute.
❌ Marking a single-syllable word (e.g. до́м)
Incorrect — one-syllable words have nowhere else for the stress to go, so they are never marked.
✅ дом
house — single syllable, no mark.
❌ Assuming real Russian text will show you the stress
Incorrect — newspapers, books, and signs have NO stress marks; you must learn each word's stress in advance.
✅ молоко (real text) = the stress you already learned from молоко́
Real text is bare; the marked form was your training wheel.
Key Takeaways
- The slanted mark (´) is the stress mark: it shows the loudest syllable of a multi-syllable word (молоко́, хорошо́, спаси́бо).
- Real Russian text has no stress marks — this guide, dictionaries, and textbooks add them as a learning aid; молоко́ is written молоко in the wild.
- The letter ё is always stressed, so it is never marked; single-syllable words are never marked either.
- Don't write the marks yourself — read them to learn each word's stress, then write bare Russian like a native.
- Learn the stress as part of the word, because Russian stress is unpredictable and controls pronunciation — start with word-stress-basics.

- The Letter ЁA2 — The letter ё is always stressed and always pronounced /jo/ or soft-consonant + 'o' — yet in everyday Russian it is routinely printed as plain е with the dots dropped, so learners must know when a written е is secretly a ё, and never read ё as 'ye'.
