Planiramo izlet za subotu.

Planiramo means we are planning or we plan.

It is the 1st person plural form of the verb planirati (to plan), so it corresponds to we in English.

• ja planiram = I plan
• ti planiraš = you plan
• on/ona planira = he/she plans
• mi planiramo = we plan
• vi planirate = you all / you formal plan
• oni planiraju = they plan

Serbian often leaves out the subject pronoun, so mi (we) is not necessary here because planiramo already shows who is doing the action.

In Serbian, the verb ending usually makes the subject clear, so subject pronouns are often omitted.

In planiramo, the ending -mo tells you the subject is we. So:

• Planiramo izlet za subotu. = We are planning a trip for Saturday.

You could say Mi planiramo izlet za subotu, but that would usually add emphasis, like We are planning a trip for Saturday.

Izlet usually means an outing, excursion, or a short trip, often for leisure and often lasting just part of a day or one day.

So in this sentence, izlet is something like:

• an outing
• a day trip
• an excursion

It is not always the best word for a long journey or major travel plan. For broader trip meanings, Serbian might also use words like putovanje (journey/travel) depending on context.

Here za means something like for, as in to schedule something for a certain time.

So:

• Planiramo izlet za subotu. = We’re planning an outing for Saturday.

This use of za + accusative is common when you mean that something is intended, arranged, or scheduled for a future time.

By contrast, u subotu usually means on Saturday in the sense of when something happens:

• Idemo na izlet u subotu. = We’re going on the trip on Saturday.

A helpful distinction:

• za subotu = for Saturday, scheduled for Saturday
• u subotu = on Saturday, happening on Saturday

Because the preposition za here requires the accusative case, and subota is a feminine noun.

The noun changes like this:

• nominative: subota = Saturday
• accusative: subotu

This is a very common pattern for feminine nouns ending in -a:

• knjiga → knjigu
• škola → školu
• subota → subotu

So za subotu is the correct form after za in this sentence.

Izlet is in the accusative case, because it is the direct object of planiramo.

We are planning what?
→ izlet

However, izlet looks the same in nominative and accusative because it is a masculine inanimate noun.

So:

• nominative: izlet
• accusative: izlet

This is very common with masculine inanimate nouns in Serbian.

Yes. Serbian word order is more flexible than English word order, although not all versions sound equally neutral.

The most neutral version here is:

• Planiramo izlet za subotu.

You could also hear:

• Izlet planiramo za subotu.
• Za subotu planiramo izlet.

These alternatives may shift emphasis:

• Izlet planiramo za subotu can emphasize the outing
• Za subotu planiramo izlet can emphasize Saturday

So the original sentence is a very natural, neutral way to say it.

Either can work.

Serbian present tense often covers both:

• we plan
• we are planning

Which English translation sounds best depends on context.

In this sentence, we are planning a trip for Saturday often feels more natural in English, because it sounds like an ongoing arrangement. But we plan a trip for Saturday is not wrong as a grammatical mapping.

Not always, but very often.

The preposition za can be used with different meanings, and in many common uses it takes the accusative, including:

• za subotu = for Saturday
• za tebe = for you
• za posao = for work

In this sentence, za means for in the sense of scheduled/intended for, so the accusative is used.

You can say:

• Mi planiramo izlet za subotu.

This means the same thing, but mi adds emphasis or contrast.

For example:

• Mi planiramo izlet za subotu, a oni za nedelju. = We’re planning a trip for Saturday, and they’re planning one for Sunday.

Without emphasis, Serbian usually prefers simply:

• Planiramo izlet za subotu.

A simple pronunciation guide is:

Pla-nee-RA-mo IZ-let za SU-bo-tu

A few notes:

• r in Serbian is rolled or tapped
• j is pronounced like English y
• stress is not usually marked in normal writing, but a learner can say this naturally with the strongest stress roughly on RA, IZ, and SU

If you say it clearly and evenly, you will be understood well.
