Я швидко пишу на клавіатурі, а миша лежить праворуч.

Yes, пишу is from писати, which literally means to write.

In Ukrainian, that verb can be used broadly for producing text, including on a computer. However, if you specifically want to emphasize typing on a keyboard, many speakers would more naturally say друкую.

So this sentence is understandable, but Я швидко друкую на клавіатурі may sound more specifically like I type quickly on the keyboard.

Because швидко is an adverb, and it describes how the action is done: quickly.

• швидкий = fast, quick as an adjective
• швидко = quickly, fast as an adverb

Here it modifies the verb пишу, so the adverb is needed.

Usually, yes.

Ukrainian often drops subject pronouns because the verb ending already shows the person:

• пишу = I write / I am writing

So Швидко пишу на клавіатурі is possible. Adding я makes the subject more explicit and can add emphasis or clarity.

It is in the locative case.

The phrase на клавіатурі means on the keyboard, and after на when talking about location, Ukrainian often uses the locative:

• клавіатура = nominative
• на клавіатурі = locative

So the ending changes because the noun is part of a location phrase.

Because на here means on or at, and it shows the location or surface connected with the action.

So:

• на клавіатурі = on the keyboard

This is the normal way to express that something is being done using the keyboard as the place/surface of typing.

Because Ukrainian has no articles.

So Ukrainian does not have separate words like a/an or the. Whether something is definite or indefinite is understood from context.

That means:

• на клавіатурі can mean on a keyboard or on the keyboard
• миша can mean a mouse or the mouse

In this sentence, the context makes it definite.

А often links two clauses with a mild contrast or topic shift.

Here it works well because the sentence is basically:

• I type quickly on the keyboard, and meanwhile the mouse is on the right.

Compare:

• і = simple and
• а = and / while / whereas with contrast or change of focus
• але = but, stronger contradiction

So а is natural here because the two parts are being set side by side.

Because а joins two separate clauses:

• Я швидко пишу на клавіатурі
• миша лежить праворуч

In Ukrainian, when two independent clauses are joined by conjunctions like а, a comma is normally used.

It can mean both.

• миша = mouse (the animal)
• миша = computer mouse

The context tells you which one is meant. Since the sentence also mentions клавіатурі, it is clearly the computer mouse here.

Yes. Ukrainian commonly uses лежати for objects that are physically resting somewhere.

So миша лежить праворуч means the mouse is lying / sitting / resting on the right. In English we often just say is, but Ukrainian often prefers a more physical verb for an object’s position.

It makes the image more concrete: the mouse is there, placed on the right side.

Праворуч means to the right or on the right-hand side.

Yes, справа is also very common and often means almost the same thing in everyday speech.

Roughly:

• праворуч = to the right / on the right
• справа = on the right / from the right side

In many contexts either works. Праворуч can sound a little more directional or slightly more formal/bookish.

They tell you the person and number.

• пишу = I write / I am writing
  • 1st person singular
• лежить = he/she/it lies / is lying
  • 3rd person singular

Because миша is the subject, лежить means it is lying.

Also, in the present tense, Ukrainian verbs do not show gender, so лежить is the same whether the singular subject is masculine, feminine, or neuter.

No, Ukrainian word order is fairly flexible.

The given order is natural and neutral:

• Я швидко пишу на клавіатурі, а миша лежить праворуч.

But you can move parts around to change emphasis:

• Я на клавіатурі швидко пишу...
• Праворуч лежить миша...

The core meaning stays similar, but the focus shifts. Ukrainian uses word order more for emphasis than English does.
