Questions & Answers about Перед вебинаром я убираю со стола лишние вещи, чтобы не отвлекаться.

Why is it Перед вебинаром and not Перед вебинар or Перед вебинара?

The preposition перед (before / in front of) requires the instrumental case.
So вебинар → вебинаром (instrumental singular).
Pattern: перед + Instrumental: перед встречей, перед уроком, перед сном.

What case is вебинаром, and how does the word decline?

Вебинаром is instrumental singular of вебинар (a masculine noun). Common singular forms:

• Nominative: вебинар
• Genitive: вебинара
• Dative: вебинару
• Accusative: вебинар
• Instrumental: вебинаром
• Prepositional: (о) вебинаре

Could I omit я? Why is it included here?

Yes, you can often omit subject pronouns in Russian because the verb ending shows the person:

• (Я) убираю = I clean away / remove.

Including я can add emphasis or clarity (e.g., contrasting with someone else, or making the sentence feel a bit more explicit).

Why is the verb убираю imperfective? Would уберу work?

убираю (imperfective) suggests a habit/routine or a process: Before the webinar, I (normally) clear extra things off the desk.
уберу (perfective) would focus on a single completed action (often “this time”): Before the webinar, I’ll clear… / I will have cleared….

So:

• Перед вебинаром я убираю… = regular practice.
• Перед вебинаром я уберу… = one-time plan/decision (context-dependent).

What does убирать mean here—“to clean” or “to remove”?

Here убирать is closer to “to remove / put away / clear away” (taking items off the surface and putting them aside).
It can also mean “to clean,” but with со стола лишние вещи the meaning is clearly “clear the desk of extra items.”

Why is it со стола and not из стола?

Because the meaning is “off the surface of the table.”

• со стола = from off the table (movement away from a surface)
• из стола = out of the table (from inside, e.g., from a drawer)

So you’d say:

• убрать со стола чашку (remove a cup from the table surface)
• достать из стола ручку (take a pen out of the desk/drawer)

Why is it со and not с?

со is a phonetic variant of с used for easier pronunciation in some contexts, especially:

• before certain consonant clusters (often с + ст…)
  So со стола is standard and very common; с стола is possible but sounds harder and less natural.

What case is стола in со стола?

It’s genitive singular.
The preposition с/со meaning “from (off)” requires the genitive:

• со стола, с полки, с крыши

Why is it лишние вещи? What does лишние mean and how does agreement work?

лишние means extra / unnecessary / not needed in this context.
It agrees with вещи in number, gender, and case:

• вещи is plural (from вещь, feminine)
• so the adjective is plural: лишние

In the sentence, лишние вещи is the direct object (accusative plural). For many inanimate plurals, accusative = nominative in form, so вещи stays вещи.

Why is вещи in that form—shouldn’t it change in the accusative?

For inanimate nouns in Russian, the accusative usually matches the nominative:

• Nominative plural: вещи
• Accusative plural (inanimate): вещи

If it were animate, you’d often see accusative = genitive (e.g., вижу людей).

What does чтобы do here, and why is the verb in the infinitive?

чтобы introduces a purpose clause: “in order to / so that”.
After чтобы, Russian often uses:

• infinitive when the subject is the same person: …чтобы не отвлекаться (so as not to get distracted)
• or a past-tense verb when it’s more like “so that (someone) would…”: …чтобы он не отвлекался.

Here the subject is the same (я), so infinitive is natural.

Why is it не отвлекаться (reflexive)? What does -ся add?

отвлекаться is the reflexive form meaning “to get distracted” (to become distracted yourself).
Without -ся, отвлекать usually means “to distract (someone else)”:

• Я не хочу отвлекаться. = I don’t want to get distracted.
• Не отвлекай меня. = Don’t distract me.

Why is there a comma before чтобы?

Because Russian typically uses a comma to separate the main clause from a subordinate clause introduced by чтобы:

• Перед вебинаром я убираю…, чтобы…

This is standard punctuation for purpose clauses.
