Government of Reflexive Verbs

You already know from the previous page that a verb in -ся is intransitive. This page draws out the single grammatical consequence that trips up nearly every learner: because the -ся has historically "absorbed" the direct object, a -ся verb can never take a noun in the accusative. So when one of these verbs still needs to point at something — the thing you fear, the subject you study, the friend you meet — it cannot do it the English way. It reaches instead for a fixed case (genitive or instrumental) or a fixed preposition + case. These are not free choices you can reason out; they are lexical government, attached to the verb like a fingerprint, and getting them right is what separates a B1 speaker from an A2 one. The most notorious of all is боя́ться: *Я бою́сь соба́ку is wrong, Я бою́сь соба́ки is right.

Why the accusative is off the table

In an ordinary active sentence, a transitive verb takes its object in the accusative: Я открыва́ю дверь "I open the door (acc.)." Add -ся and the verb stops being able to do that — дверь открыва́ется "the door opens" has no object at all. The slot that the accusative used to fill is gone. But meaning doesn't vanish: боя́ться still has something feared, занима́ться still has something studied. Russian fills that role with a different case, chosen by the verb. Think of it as the verb saying, "I refuse the accusative — bring me the genitive instead," or "bring me the instrumental."

Verbs that govern the genitive

A small but very frequent group takes the genitive. The two you must own at B1 are боя́ться "to fear" and каса́ться "to concern / to touch (a topic)."

Verbs that govern the instrumental — the big group

This is the largest and highest-yield set, and the one that feels least intuitive to English speakers, because English uses a plain object where Russian demands the instrumental. "I study Russian," "I'm interested in history," "I use a computer" — all bare objects in English, all instrumental in Russian.

The thread tying these together is that the instrumental marks the thing through which / by means of which you are occupied — exactly the means-and-instrument logic of the case. You are "busy with sport", "occupy yourself by means of music." Internalise that and the bare instrumental stops feeling arbitrary.

Verbs that govern a preposition

The third group locks each verb to a specific preposition + case. There is no logic that predicts which preposition — you memorise the pairing — but the set below covers the high-frequency B1 verbs, and the preposition-governing verbs page lists the rest.

The с-group is worth a special note. The reciprocal verbs (встреча́ться "meet", проща́ться "say goodbye", здоро́ваться "greet", сове́товаться "consult") naturally pair with с + instrumental, because you do the action with another person — встреча́ться с друзья́ми, проща́ться с ба́бушкой.

How this differs from English

English verbs of this kind use either a bare object ("I study Russian," "I use a phone," "I fear dogs") or a transparent preposition that maps cleanly ("interested in," "proud of"). Two traps follow. First, the English bare object lures you toward the Russian accusative — but боя́ться, занима́ться, интересова́ться all reject it, taking genitive or instrumental instead. Second, even where English has a preposition, it rarely matches the Russian one: English "laugh at" is Russian смея́ться над (+ instr.), English "prepare for" is гото́виться к (+ dat.), English "count on" is наде́яться на (+ acc.). You cannot translate the preposition; you must store the whole verb-plus-government as one unit.

Common Mistakes

Key Takeaways

• A -ся verb is intransitive: it can never take an accusative direct object. The object slot is gone, so the verb governs a different case or a preposition.
• Genitive-governing: боя́ться (бою́сь темноты́), каса́ться, добива́ться.
• Instrumental-governing (the big one — English uses a bare object): занима́ться спо́ртом, интересова́ться исто́рией, по́льзоваться словарём, горди́ться сы́ном.
• Preposition-governing: наде́яться на (+ acc.), смея́ться над (+ instr.), относи́ться к / гото́виться к (+ dat.), сомнева́ться в / нужда́ться в (+ prep.), отказа́ться от (+ gen.), встреча́ться с (+ instr.).
• These are fixed lexical government, not optional — store each verb together with its case. The canonical error is *бою́сь соба́ку → бою́сь соба́ки.
