The Second Locative (в лесу, на берегу)

If you have learned that the prepositional singular of masculine nouns is -е (в столе́, в до́ме), you have learned the rule that covers 95% of cases — and you have also learned the rule that will make you say the wrong thing for some of the most ordinary words in the language. A closed set of roughly a hundred masculine nouns takes a special, always-stressed -у́ / -ю́ after в and на when those prepositions mean physical location ("in / on"). This is the second locative (also called the locative-2 or, in Russian school terms, the ме́стный паде́ж, méstny padézh, "the locative case"). It is not a seventh case you have to learn from scratch — it is a small subset of the prepositional that hijacks the ending of about a hundred words. The trouble is that those hundred words include в лесу́ (in the forest), на берегу́ (on the bank), в саду́ (in the garden), на полу́ (on the floor), and the unavoidable в э́том году́ (this year). Skip this page and you will be saying в лесе, на бе́реге, *в этом годе for the rest of your Russian life — and every native speaker will hear it.

The core fact: stressed -у́ after в/на for location

For the locative-2 nouns, the prepositional ending after в ("in") or на ("on") is -у́ (hard stems) or -ю́ (soft stems), and it is always stressed — the stress jumps onto the ending. Compare the regular pattern (-е, often unstressed) with the locative-2:

Noun (nominative)	Regular -е (would-be)	Second locative (после в/на)	Meaning
лес (forest)	*в ле́се	в лесу́	in the forest
бе́рег (bank, shore)	*на бе́реге	на берегу́	on the bank / shore
сад (garden)	*в са́де	в саду́	in the garden
пол (floor)	*на по́ле	на полу́	on the floor
у́гол (corner)	*в у́гле	в углу́	in the corner
год (year)	*в го́де	в году́	in the year

Мы заблуди́лись в лесу́ и два часа́ иска́ли доро́гу.

We got lost in the forest and spent two hours looking for the way out. (second locative: лес → в лесу́, stressed -у́)

Де́ти весь день игра́ли на берегу́.

The kids played on the shore all day. (берег → на берегу́, stressed -у́)

Кни́га упа́ла и лежи́т на полу́.

The book fell and is lying on the floor. (пол → на полу́, stressed -у́)

💡

The stress is the giveaway. The regular prepositional -е is frequently unstressed (в до́ме, в го́роде); the second locative -у́ is never unstressed. If you hear a Russian say a place ending in a stressed -у́ after в or на, you have just heard a locative-2.

Why English speakers never see this coming

English marks "in the forest" and "about the forest" with the same noun form — the preposition does all the work, and forest never changes. Russian already surprises you by changing the ending to -е after a preposition; the second locative adds a second twist that no Romance or Germanic language prepares you for: the very same noun has two different prepositional endings depending on what the preposition means. "In the forest" (location) is в лесу́, but "about the forest" (topic) is о ле́се. There is no logic you can derive from English here — it is a frozen relic of an older Slavic case system that, over centuries, collapsed two distinct cases (a locative and a prepositional) into one for most nouns but left these hundred-odd masculine words carrying the old stressed ending. You simply have to know which words are in the club.

The decisive contrast: location vs. topic

Here is the rule that locks the whole thing in. The second locative appears only with в/на in a locational sense. The moment the noun is the topic of speech or thought — that is, after о/об ("about") — it reverts to the perfectly regular -е. Same with the genitive, dative, and so on elsewhere in the sentence. The locative-2 is triggered by в/на + place, nothing else.

Location (в/на) → locative-2	Topic (о) → regular -е
в лесу́ — in the forest	о ле́се — about the forest
в саду́ — in the garden	о са́де — about the garden
в году́ — in the year	о го́де — about the year
на берегу́ — on the bank	о бе́реге — about the bank

В лесу́ ти́хо, а вот пи́шут о ле́се у́жасы.

It's quiet in the forest, but the things they write about the forest are awful. (location: в лесу́, stressed -у́; topic: о ле́се, regular -е)

Мы говори́ли о про́шлом го́де, кото́рый провели́ в Сиби́ри.

We were talking about last year, which we spent in Siberia. (topic: о го́де, regular -е — NOT *о году́)

💡

Build the contrast as a pair in your head: в лесу́ but о ле́се, в году́ but о го́де. Once you can flip between them on demand, you have understood the locative-2 better than most textbooks ever explain it: it is not "an irregular noun," it is a noun with a special location form and an ordinary topic form.

The high-frequency members you must know

You do not need to memorize all hundred. Most of them are uncommon. But a few dozen are so frequent that getting them wrong marks you instantly as a learner. Group them and overlearn them:

Group	Members (locative-2 form)
Nature / outdoors	в лесу́, на берегу́, в саду́, на ветру́ (in the wind), в снегу́ (in the snow), на льду (on the ice), в раю́ (in paradise), в аду́ (in hell)
Around the room / building	на полу́ (on the floor), в углу́ (in the corner), в шкафу́ (in the cupboard), на краю́ (on the edge), в ряду́ (in a row)
Places / structures	на мосту́ (on the bridge), в порту́ (in the port), в аэропорту́ (at the airport), на посту́ (at one's post), в плену́ (in captivity), в бою́ (in battle)
Time / abstract	в году́ (in the year), в э́том году́ (this year), в про́шлом году́ (last year), в нача́ле / в конце́ (regular!), на ходу́ (on the move)

В э́том году́ мы е́здили в о́тпуск два ра́за.

This year we went on holiday twice. (год → в году́; this is the single most common locative-2 you will ever use)

Твоя́ ку́ртка в шкафу́, на ве́рхней по́лке.

Your jacket is in the cupboard, on the top shelf. (шкаф → в шкафу́)

Мы стоя́ли на мосту́ и смотре́ли на ло́дки в порту́.

We stood on the bridge looking at the boats in the harbour. (мост → на мосту́, порт → в порту́)

Маши́на е́ле е́хала по доро́ге в снегу́.

The car was barely moving along the road in the snow. (снег → в снегу́)

Honest difficulty: variation and meaning-shifts

This is one of those corners of Russian where you have to accept some genuine messiness. Three honest warnings:

1. Some nouns allow both forms, with a meaning difference. The classic pair is ряд: в ря́де слу́чаев ("in a number of cases", abstract) vs. в ряду́ ("in the row", physical line). Likewise в кру́ге (in a circle, geometry) vs. в кругу́ (in the circle/midst of, e.g. в кругу́ друзе́й "among friends"). The locative-2 tends to carry the concrete, spatial meaning; the regular -е carries the abstract one.

В ря́де слу́чаев э́то пра́вило не рабо́тает.

In a number of cases this rule doesn't work. (abstract 'a number of' → regular -е: в ря́де)

Он стоя́л в пе́рвом ряду́ и всё ви́дел.

He was standing in the first row and could see everything. (physical row → locative-2: в ряду́)

2. Some nouns are drifting. For a few words the locative-2 is optional and slightly old-fashioned, with the regular -е gaining ground (e.g. в отпуске / в отпуску́ — the -е form is now standard, the -у́ is colloquial/dated). When in doubt with a less common noun, the regular -е is the safer bet; you will only sound bookish, never wrong.

3. There is no derivable rule for membership. You cannot predict from a noun's shape whether it is a locative-2 word. Лес is, but го́род ("city") is not (в го́роде, regular). You memorize the list. There is genuinely no shortcut here — but the good news is the list is closed and the frequent members are few.

Я весь день рабо́тал в саду́, а ве́чером отдыха́л в кругу́ семьи́.

I worked in the garden all day, and in the evening I relaxed in the bosom of my family. (сад → в саду́; круг → в кругу́, the 'midst of' meaning)

Common Mistakes

❌ Мы гуля́ли в ле́се.

Incorrect — лес is a second-locative noun; location after в is в лесу́, not the regular -е.

✅ Мы гуля́ли в лесу́.

We were walking in the forest. (в лесу́, stressed -у́)

❌ В про́шлом го́де я был в Москве́.

Incorrect — 'in the year X' uses the locative-2: в году́. The -е form is only for the topic о го́де.

✅ В про́шлом году́ я был в Москве́.

Last year I was in Moscow. (в году́; note Москве́ is a regular -е — most nouns are NOT locative-2)

❌ Ребёнок сиди́т на по́ле.

Incorrect — that means 'in the field' (по́ле, a different noun); 'on the floor' is пол → на полу́.

✅ Ребёнок сиди́т на полу́.

The child is sitting on the floor. (пол → на полу́, stressed -у́)

❌ Мы до́лго говори́ли о лесу́.

Incorrect — the second locative appears ONLY with в/на for location. The topic after о takes the regular -е: о ле́се.

✅ Мы до́лго говори́ли о ле́се.

We talked for a long time about the forest. (topic → о ле́се, regular -е)

❌ в лесе́

Incorrect — never stress the regular -е onto a locative-2 noun trying to 'fix' it. The form is в лесу́; the -е form в ле́се (if used at all) is stem-stressed.

✅ в лесу́

in the forest (one word, one stress, on the ending -у́)

Key Takeaways

The second locative (locative-2) is a closed set of ~100 mostly masculine nouns that take a stressed -у́ / -ю́ after в / на meaning physical location, instead of the regular -е.
It is not a new case — it is a special subset of the prepositional. The endings tables call the rest of the prepositional -е; these words are the exceptions.
It appears only with в/на for location. After о ("about"), or anywhere else, the noun reverts to the regular -е: в лесу́ but о ле́се, в году́ but о го́де.
Overlearn the frequent members: в лесу́, на берегу́, в саду́, на полу́, в углу́, в шкафу́, на мосту́, в порту́, в аэропорту́ — and above all в э́том году́ / в про́шлом году́.
Membership is not predictable and a few nouns vary or shift meaning (в ря́де vs в ряду́, в кру́ге vs в кругу́). Memorize the list; with rare words the regular -е is the safe default.
