Pomerili smo izlet za subotu.

Because Serbian often drops subject pronouns when they are already clear from the verb form.

In Pomerili smo, the word smo shows 1st person plural (we have / we did), so mi is not necessary.

• (Mi) smo pomerili = we moved / we postponed

If you add mi, it usually gives extra emphasis, like:

• Mi smo pomerili izlet za subotu. = We moved the trip to Saturday.

This is because smo is a clitic in Serbian, and clitics usually go in the second position of the sentence or clause.

So in a neutral sentence, Serbian often puts the past participle first and the clitic second:

• Pomerili smo izlet za subotu.

But word order can change for emphasis, as long as the clitic stays in an appropriate second-position slot:

• Izlet smo pomerili za subotu.
• Za subotu smo pomerili izlet.

So pomerili smo is a very normal and natural order.

It is the past tense form, made with:

• the L-participle: pomerili
• the auxiliary biti in the present tense: smo

So:

• pomerili smo = we moved / we have moved

The dictionary form of the verb is pomeriti.

This form is commonly used for completed actions in the past.

The participle agrees with the gender and number of the subject.

Here, pomerili smo is used when the subject is:

• a group of men, or
• a mixed-gender group, or
• a group whose gender is unspecified in standard default usage

If the speakers were all female, it would be:

• Pomerile smo izlet za subotu.

So the ending tells you something about the speakers.

Izlet is the direct object of the verb, so it is in the accusative case.

But izlet is a masculine inanimate noun, and for many masculine inanimate nouns, the accusative singular looks the same as the nominative singular.

So:

• nominative: izlet
• accusative: izlet

That is why it looks unchanged.

Compare this with a masculine animate noun, where accusative would usually be different.

Subotu is in the accusative case.

The preposition za often takes the accusative, and in this sentence za subotu means something like:

• for Saturday
• in context, to Saturday

When talking about rescheduling something, Serbian commonly uses:

• pomeriti nešto za + accusative

So:

• Pomerili smo izlet za subotu. = We moved/postponed the trip to Saturday.

Here:

• nominative: subota
• accusative: subotu

Literally, it looks like for Saturday, but in this context the natural meaning is:

• to Saturday

This is a common Serbian way to express that an event has been rescheduled.

So if an English speaker sees for Saturday, that can be misleading. In this sentence, the idea is not just planning something for Saturday, but specifically moving it so that it will happen on Saturday.

Because u subotu and za subotu do not mean exactly the same thing here.

• u subotu = on Saturday
• za subotu in this sentence = to Saturday / for Saturday as the new scheduled time

So:

• Izlet je u subotu. = The trip is on Saturday.
• Pomerili smo izlet za subotu. = We moved the trip to Saturday.

The second sentence emphasizes the change of schedule, not just the day when it happens.

Often yes, in this kind of context.

The verb pomeriti basically means to move / shift. When used with plans, appointments, trips, meetings, and dates, English often translates it as:

• move
• reschedule
• sometimes postpone

So depending on context, this sentence could sound like:

• We moved the trip to Saturday.
• We rescheduled the trip for Saturday.

If Saturday is later than the original date, then in English postponed may also fit.

Pomeriti is a perfective verb.

That means it presents the action as completed: the trip was successfully moved to a new date.

Its imperfective partner is usually pomerati.

Compare:

• Pomerili smo izlet za subotu. = We moved the trip to Saturday.
  Completed result.
• Pomerali smo izlet više puta. = We were moving/rescheduling the trip several times.
  Repeated or ongoing action.

Aspect is very important in Serbian because it tells you how the action is viewed, not just when it happened.

Yes. Serbian word order is fairly flexible, but the meaning emphasis changes.

For example:

• Pomerili smo izlet za subotu.
  Neutral.
• Izlet smo pomerili za subotu.
  Focus on the trip.
• Za subotu smo pomerili izlet.
  Focus on Saturday.

The main thing to remember is that the clitic smo still has to stay in an appropriate second position.

Yes. Izlet often means:

• trip
• outing
• excursion

It usually suggests a relatively short trip, often for pleasure, nature, school, or a day out, rather than a long journey.

So depending on context, English might translate it differently, even though the Serbian word stays the same.
