Ґудзик лежить біля нитки.

Because біля requires the genitive case.

The base form is нитка (thread). After біля (near, by), it changes to нитки, which is the genitive singular form.

So:

• нитка = thread
• біля нитки = near the thread

This is a very common pattern in Ukrainian:

• біля столу = near the table
• біля машини = near the car
• біля нитки = near the thread

Ґудзик is in the nominative singular because it is the subject of the sentence — the thing that is doing the action or being described.

In this sentence:

• ґудзик = the button
• лежить = lies / is lying
• біля нитки = near the thread

So ґудзик is the thing that lies somewhere.

Ukrainian often prefers a position verb where English might simply say is.

So instead of saying something like The button is near the thread, Ukrainian naturally says:

• Ґудзик лежить біля нитки.

The verb лежати means to lie or to be lying, and it is commonly used for objects that are resting somewhere.

This is very natural in Ukrainian. It often sounds more specific and vivid than a plain to be.

Usually, yes. Лежати often suggests that something is in a lying position, resting on a surface.

For small objects like a button, this is very natural. A button on a table, floor, or piece of cloth would normally лежить.

Ukrainian often distinguishes position more clearly than English:

• лежати = to lie
• стояти = to stand
• сидіти = to sit

So the sentence does not just say where the button is — it also suggests its physical position.

Біля means near, by, or next to.

It shows location relative to something else. In this sentence:

• біля нитки = near the thread

It does not necessarily mean direct contact. It just means the button is close to the thread.

Other Ukrainian words can also express similar ideas, such as:

• коло
• поруч із

But біля is very common and natural.

Yes. Ukrainian word order is more flexible than English word order because case endings show grammatical relationships.

The neutral order here is:

• Ґудзик лежить біля нитки.

But you could also say:

• Біля нитки лежить ґудзик.

This might put a little more focus on the location first: Near the thread, there is a button lying.

The meaning stays basically the same, though emphasis can shift.

• ґудзик is masculine
• нитка is feminine

This matters because gender affects how words change in different cases and how other words agree with them.

For example:

• нитка is feminine, so its genitive singular becomes нитки
• ґудзик is masculine, and here it stays in the nominative singular as the subject

A helpful approximation is GOOD-zyk, though not exactly like English.

Important points:

• ґ is a hard g sound, like in go
• у sounds roughly like oo in boot
• дз is pronounced like the ds sound in adds
• и is a short Ukrainian vowel that does not match English exactly; it is not the same as ee

So ґудзик is roughly GOO-dzyk.

A very important note: ґ and г are different letters in Ukrainian.

• ґ = hard g
• г = a softer sound, somewhat like a voiced h

Because Ukrainian distinguishes between two different consonants:

• г = a sound somewhat like a soft, voiced h
• ґ = a true g sound

In ґудзик, the word uses the real g sound, so it is written with ґ.

This is something English speakers often notice early because many Ukrainian words use г, while some use ґ.

Ukrainian does not have articles like a and the.

So ґудзик can mean:

• a button
• the button

And нитки can mean:

• of a thread
• of the thread

Context tells you which meaning is intended.

That is normal in Ukrainian, and learners need to get used to understanding definiteness from context rather than from articles.

Yes, absolutely. In fact, it is very common.

Ukrainian frequently uses лежати for objects that are resting somewhere:

• Книга лежить на столі. = The book is lying on the table.
• Телефон лежить у сумці. = The phone is lying in the bag.
• Ґудзик лежить біля нитки. = The button is lying near the thread.

So this use is completely natural.

The dictionary form is лежати, which means to lie or to be lying.

Лежить is the 3rd person singular form:

• він лежить = he/it lies
• вона лежить = she/it lies
• воно лежить = it lies

Here it agrees with ґудзик, which is singular, so лежить is the correct form.

Grammatically, є means is, but in a sentence like this, є would usually sound less natural than лежить.

For physical location, especially with an object resting somewhere, Ukrainian strongly prefers a more specific verb like лежить.

So:

• Ґудзик лежить біля нитки. = natural
• Ґудзик є біля нитки. = much less natural in this context

In everyday Ukrainian, є is not usually used the same way English uses is in simple location sentences.
