Тітка в окулярах завжди приносить нам пиріг.

Because after в meaning in / wearing / with, Ukrainian often uses the locative case.

• dictionary form: окуляри = glasses
• locative plural: в окулярах = in glasses / wearing glasses

So тітка в окулярах literally means the aunt in glasses, which is the natural Ukrainian way to say the aunt with glasses or the aunt wearing glasses.

A few similar examples:

• чоловік у капелюсі = the man in a hat
• дівчина в черевиках = the girl in boots

Yes, окуляри is normally a plural-only noun in Ukrainian, just like English glasses.

So you say:

• мої окуляри = my glasses
• немає окулярів = there are no glasses
• в окулярах = in glasses / wearing glasses

You normally do not use a singular form for ordinary eyeglasses.

Нам is the dative case form of ми (we).

• ми = we
• нас = us
• нам = to us / for us

The verb приносити / принести often takes:

• the thing being brought
• the person it is brought to

So:

• приносить пиріг = brings a pie
• приносить нам пиріг = brings us a pie / brings a pie to us

This is very similar to English indirect objects.

It is accusative, but for many inanimate masculine nouns, the accusative singular looks the same as the nominative singular.

So:

• nominative: пиріг
• accusative: пиріг

That is why the form does not visibly change.

Compare:

• Я бачу стіл. = I see a table.
  (стіл stays the same in the accusative because it is inanimate masculine)

But with an animate masculine noun:

• Я бачу брата. = I see my brother.
  Here the accusative changes.

Приносить is the imperfective verb meaning brings / is bringing / habitually brings.

In this sentence, завжди = always, so the action is habitual. That makes приносить the natural choice:

• Тітка завжди приносить... = The aunt always brings...

Compare:

• приносити / приносить = to bring, to be bringing, to bring regularly
• принести / принесе = to bring once, to bring and complete the action

So:

• Вона завжди приносить пиріг. = She always brings pie.
• Вона завтра принесе пиріг. = She will bring pie tomorrow.

And носити is different: it means to carry regularly / wear / take around, without the при- idea of bringing toward someone/somewhere.

Yes, приносить is grammatically present tense, but in Ukrainian, just like in English, the present tense can describe a habitual action.

Because of завжди (always), the sentence means something like:

• she always brings
• she regularly brings
• she tends to bring

So it is present tense in form, but habitual in meaning.

Yes, Ukrainian word order is fairly flexible, and завжди can move depending on emphasis.

The neutral version is:

• Тітка в окулярах завжди приносить нам пиріг.

But you could also hear:

• Завжди тітка в окулярах приносить нам пиріг.
• Тітка в окулярах приносить нам завжди пиріг.
  (less neutral, more marked)

The most natural order here is the original one because:

• the subject comes first
• завжди naturally sits near the verb
• the sentence sounds smooth and neutral

So this is mostly about information structure and emphasis, not a grammar rule that allows only one order.

It can do both, depending on context.

In a sentence like this, тiтка в окулярах is usually understood as a describing phrase attached to тiтка:

• the aunt with glasses
• the aunt wearing glasses

It helps identify which aunt is being talked about. It may describe her usual appearance, or just how she appears in the situation. Context decides that.

So grammatically it works like a noun + descriptive phrase:

• жінка в пальті = the woman in a coat
• хлопець у шапці = the boy in a hat

Ukrainian has no articles like English a/an and the.

So тітка can mean:

• an aunt
• the aunt

And пиріг can mean:

• a pie
• the pie

You figure out which one is meant from context, word order, and general situation.

In this sentence, English often uses the aunt because the descriptive phrase в окулярах makes it sound like a specific person. But Ukrainian does not need an article.

Тітка literally means aunt, but in real usage it can also refer to an older woman, sometimes informally.

Possible uses:

• your actual aunt
• a woman of your parents’ generation, in casual speech
• sometimes even a slightly colloquial lady / woman

However, in a basic sentence like this, learners should first understand it as aunt unless context suggests otherwise.

A simple English-friendly guide:

• тітка ≈ TEET-ka
• пиріг ≈ py-rih

A few notes:

• і sounds like ee in see
• и is a short central vowel, not exactly English ee or ih
• г in Ukrainian is usually a softer sound than English g; in many cases it sounds closer to a voiced h

Stress:

• тІтка
• пирІг

So the stressed syllables are:

• ТІТ-ка
• пи-РІГ

Usually в окулярах is much more natural for wearing glasses.

• тітка в окулярах = the aunt wearing glasses / the aunt with glasses

з окулярами would sound more like:

• with glasses in her possession
• accompanied by glasses
• associated with glasses in some less natural way

So for clothing and things worn on the body, Ukrainian commonly prefers в or у + locative:

• в окулярах
• у пальті
• в шапці

In writing it is в, but in speech Ukrainian often alternates between в and у for ease of pronunciation.

So you may see or hear:

• в окулярах
• у окулярах

Both are normal. Writers and speakers often choose whichever sounds smoother with surrounding words.

After тітка, many people would naturally say в окулярах, but у окулярах is also possible in many contexts. This alternation is about euphony, not a change in meaning.
