Questions & Answers about Я сижу на диване.

What verb form is сижу? Which dictionary form does it come from, and is it irregular?

Сижу is the 1st person singular, present tense form of the verb сидеть (to sit, to be sitting).

Full present-tense paradigm of сидеть:

• я сижу – I sit / I am sitting
• ты сидишь – you sit / you are sitting (sg., informal)
• он / она / оно сидит – he / she / it sits / is sitting
• мы сидим – we sit / are sitting
• вы сидите – you sit / are sitting (pl. or polite)
• они сидят – they sit / are sitting

It is slightly irregular because the stem changes:

• dictionary stem: сид- (сидеть)
• 1st person singular stem: сиж- (сижу)

You just have to memorize this pattern for this verb.

Does Я сижу mean “I am sitting” or “I sit”? How does Russian express the English continuous tense?

Я сижу can mean both:

• I am sitting (right now).
• I sit (habitually / regularly).

Russian does not have a special present continuous tense like English. The same present tense form covers:

• actions happening right now,
• regular or habitual actions.

Context or adverbs usually clarify:

• Сейчас я сижу на диване. – Right now I am sitting on the sofa.
• Каждый вечер я сижу на диване. – Every evening I sit on the sofa.

Why is it на диване and not на диван or в диване?

There are two main points: the preposition and the case.

1. На vs в

   • на = on (a surface): на диване, на столе (on the table), на стуле (on the chair)
   • в = in / inside: в комнате (in the room), в шкафу (in the cupboard)

   You sit on a sofa, so Russian uses на.

2. Location (where?) vs direction (onto / to where?)

   • на + prepositional case = location, no movement:
     
     • Я сижу на диване. – I am sitting on the sofa. (where?)
   • на + accusative case = direction / movement onto:
     
     • Я сажусь на диван. – I am sitting down on the sofa. (onto where?)

So:

• на диване – on the sofa (already there, no movement)
• на диван – onto the sofa (movement)
• в диване – literally “inside the sofa” (only in odd, physical contexts, e.g. The money is inside the sofa).

What grammatical case is диване, and how is it formed from диван?

Диване is the prepositional case singular of диван.

Диван is a masculine noun ending in a consonant. Its main singular cases are:

• Nominative (who? what?): диван – the sofa
• Genitive (of what?): дивана – of the sofa
• Dative (to what?): дивану – to the sofa
• Accusative (what?): диван – the sofa (same as nominative for inanimate nouns)
• Instrumental (with what?): диваном – with / by means of the sofa
• Prepositional (about / in / on what?): (на) диване, (о) диване – on / about the sofa

After на in the meaning of on (where?), you use the prepositional case, hence на диване.

Can I omit я and just say Сижу на диване? Is that natural?

Yes. Сижу на диване is perfectly natural Russian.

In Russian, the personal pronoun (я, ты, он, etc.) is often dropped when the verb ending already shows the person clearly. You use я mainly:

• to emphasize the subject: Я сижу на диване, а не он. – I’m the one sitting on the sofa, not him.
• to avoid ambiguity, or in contrast: Я сижу, а ты стоишь.

In a neutral, simple context, both:

• Я сижу на диване.
• Сижу на диване.
  are fine.

Can I change the word order (e.g. На диване я сижу, Я на диване сижу)? Does it change the meaning?

Yes, Russian allows fairly free word order. All of these are grammatical, but the emphasis changes slightly:

• Я сижу на диване. – most neutral; a simple statement.
• Я на диване сижу. – mild emphasis on “on the sofa” (not somewhere else).
• На диване я сижу. – stronger focus on the location; often a contrast:
  
  • На диване я сижу, а он стоит у окна. – On the sofa I’m sitting, and he’s standing by the window.

In everyday speech, the most common neutral version is Я сижу на диване (or without я). The others are used when you want a particular nuance or rhythm.

What’s the difference between Я сижу на диване and Я на диване?

• Я сижу на диване.

  • Explicitly says you are sitting (not lying, not standing).
  • Describes both posture and location.

• Я на диване.

  • Only says where you are, not how: you could be sitting, lying, kneeling, etc.
  • Typical as a short answer to Where are you?
    
    • – Ты где? – Я на диване. – Where are you? – I’m on the sofa.

So Я сижу на диване gives more detail by specifying the posture.

When do I use сидеть vs лежать vs стоять when talking about where I am?

These three verbs describe posture / position:

• сидеть – to sit, be in a sitting position
  
  • Я сижу на диване. – I am sitting on the sofa.
• лежать – to lie, be lying down
  
  • Я лежу на диване. – I am lying on the sofa.
• стоять – to stand, be standing
  
  • Я стою у окна. – I am standing by the window.

Russian often prefers these posture verbs where English might just say to be:

• English: The book is on the table.
• Russian: Книга лежит на столе. (literally “the book lies on the table”)

For people:

• Он сидит за столом. – He is sitting at the table.
• Он стоит у двери. – He is standing by the door.

Using the correct posture verb sounds more natural than always using быть (to be).

How do I talk about the action of “sitting down on the sofa” instead of just “being in a sitting position on the sofa”?

To express “sit down (onto the sofa)”, Russian usually uses садиться / сесть (to sit down), not сидеть.

• Ongoing / process (imperfective):

  • Я сажусь на диван. – I am sitting down on the sofa / I am taking a seat on the sofa.

• Single completed action (perfective future / intention):

  • Я сяду на диван. – I’ll sit down on the sofa.

• Past completed action:

  • Я сел на диван. – I sat down on the sofa.

Compare:

• Я сижу на диване. – I am sitting on the sofa (already in the sitting position).
• Я сел на диван. – I sat down on the sofa (the moment of moving into that position).

Why does сидеть become сижу? Where does the ж come from?

This is a stem change that happens in some Russian verbs ending in -деть / -дить. In the 1st person singular, д changes to ж.

Сидеть:

• stem in dictionary form: сид-
• 1st person singular: сиж-
  • у → сижу

Other verbs show the same pattern:

• видеть → я вижу (not видю) – I see
• ходить → я хожу (not ходю) – I go (on foot)
• следить → я слежу – I watch / I follow

You can think of сижу as a partly irregular form you must memorize along with the verb.

What exactly is a диван in Russian compared to English words like “sofa”, “couch”, “armchair”, and “chair”?

Диван is basically what English speakers call a sofa or couch: a long, soft piece of furniture where several people can sit (and often lie down).

Related words:

• кресло – armchair (a big, comfy chair for one person, usually with arms)
• стул – chair (simple chair, usually without soft upholstery)
• кровать – bed

So:

• Я сижу на диване. – I’m sitting on the sofa / couch.
• Я сижу в кресле. – I’m sitting in the armchair.
• Я сижу на стуле. – I’m sitting on the chair.
