Jutro jemy kolację u cioci.

In Polish, the present tense is very often used for planned future events, just like in English in sentences such as We’re having dinner tomorrow.

So Jutro jemy kolację u cioci literally uses the present form jemy = we eat / we are eating, but with jutro (tomorrow) it naturally means we’re eating / having dinner tomorrow.

This is especially common when talking about arrangements, plans, schedules, or intentions.

Because Polish verb endings usually already show who is doing the action.

Jemy means we eat / we are eating, so the pronoun my (we) is not necessary.

You could say My jutro jemy kolację u cioci, but that usually adds emphasis, like We are the ones eating at our aunt’s tomorrow.

Because kolację is in the accusative case, which is used for the direct object of the verb.

Here, the thing being eaten/had is dinner, so Polish uses the accusative:

• nominative: kolacja = dinner
• accusative: kolację

So:

• Jemy kolację = We’re eating/having dinner

This is very common in Polish: the object of the verb often changes form.

U cioci means at auntie’s / at our aunt’s place.

The preposition u is often used when talking about being at someone’s home, place, business, or with that person.

So:

• u cioci = at auntie’s
• u mamy = at mom’s
• u lekarza = at the doctor’s

It does not literally mean inside aunt or anything like that. It is a normal Polish structure for location connected with a person.

Because the preposition u requires the genitive case.

The basic form is:

• ciocia = aunt / auntie

But after u, it changes to:

• u cioci = at auntie’s

So this is another case change:

• nominative: ciocia
• genitive: cioci

It is usually closer in feeling to auntie than to the more neutral aunt.

Ciocia is a warm, familiar, everyday word. In family speech, Polish often prefers these affectionate forms.

So u cioci sounds natural and family-like, not overly formal.

Putting jutro first emphasizes the time: Tomorrow we’re having dinner at our aunt’s.

Polish word order is fairly flexible, so you could also say:

• Jemy jutro kolację u cioci
• Kolację jemy jutro u cioci
• U cioci jemy jutro kolację

But Jutro jemy kolację u cioci is very natural because it introduces the time first.

It can mean both, depending on context.

In natural English, have dinner is often the best translation, but Polish uses the verb jeść (to eat) in this kind of sentence.

So:

• Jemy kolację = We’re eating dinner / We’re having dinner

The exact English wording depends on what sounds most natural.

It is neutral and everyday.

Nothing in it is especially formal. The use of cioci makes it sound natural and family-oriented.

A very formal version would probably avoid this exact kind of family phrasing unless the context were personal.

Sometimes in context it can imply both, but the main idea is location connected with her—usually at her place.

If you want to say clearly with auntie in the sense of accompanying her, Polish often uses z ciocią (with auntie).

Compare:

• Jemy kolację u cioci = We’re having dinner at auntie’s
• Jemy kolację z ciocią = We’re having dinner with auntie

Sometimes both may be true in real life, but the grammar points in different directions.

Cioci is pronounced approximately like CHO-chee, but with a softer Polish sound.

A rough breakdown:

• cio sounds a bit like cho
• ci at the end sounds like a soft chee

Polish ci is a soft consonant sound, so it is lighter than normal English ch.

You can, but the result may sound slightly unnatural.

Word for word:

• Jutro = tomorrow
• jemy = we eat / we are eating
• kolację = dinner
• u cioci = at auntie’s

A literal version would be:

• Tomorrow we eat dinner at auntie’s

But more natural English would usually be:

• We’re having dinner at our aunt’s tomorrow
• Tomorrow we’re having dinner at our aunt’s

So the Polish grammar and the English grammar do not match perfectly word for word.
