Molim te, pokupi mrvice kruha sa stola.

Molim te literally means I’m asking you / I beg you:

• molim = (I) ask / (I) request (1st person singular present of moliti)
• te = you (object pronoun, accusative/genitive clitic)

In everyday Croatian, Molim te, … is a very common way to say Please, … before a request.

Because Molim te works like an introductory phrase (a discourse marker) before the main request. In writing, it’s typically set off with a comma:

• Molim te, pokupi …

In casual texting, people sometimes omit the comma, but the comma is standard.

Yes. pokupi is the 2nd person singular imperative of pokupiti (to pick up / gather up). It’s used when speaking to one person informally (ti).

If you’re addressing:

• one person formally or multiple people: pokupite
• a group including yourself: pokupimo (let’s pick up)

The prefix helps create a verb meaning to pick up (everything / thoroughly / all the scattered bits). With crumbs, pokupiti strongly suggests collecting them up rather than just touching/moving them.

A common imperfective partner is pokupljati (repeated/ongoing: to be picking up / to pick up habitually).

te is a clitic (a weak pronoun) and Croatian clitics have special placement rules: they usually come very early in the clause (often in the “second position”).

Here it naturally follows Molim:

• Molim te, …

You can also place te with the main verb in some contexts, but it changes the feel and structure. The most natural for please is exactly Molim te, ….

mrvice is accusative plural (direct object) of mrvica (crumb). The verb pokupiti takes a direct object (“pick up what?”), so you use accusative:

• pokupi (što?) mrvice

mrvica is feminine; plural mrvice is very common when you mean “crumbs” in general.

Because kruha is genitive singular of kruh (bread) and here it’s a very common “noun + genitive” pattern meaning crumbs of bread (a kind/type/source relationship).

So:

• mrvice kruha = bread crumbs / crumbs of (some) bread

In practice, it functions like bread as a substance/material: crumbs of bread. Genitive often appears in these “substance/source” phrases, and it can overlap with a partitive feeling (“some bread”), but the natural English equivalent is simply bread crumbs.

Yes. Pokupi mrvice sa stola. is perfectly natural and often enough if it’s obvious what kind of crumbs they are. Adding kruha just specifies bread (not cake, cookies, etc.).

Because sa/s with the genitive means off (of) / from (a surface):

• pokupi … sa stola = pick … up off the table

na stolu means on the table (location), not removal:

• mrvice su na stolu = the crumbs are on the table

Both s and sa mean with or from/off depending on context, but sa is often used:

• before certain consonant clusters (for easier pronunciation)
• optionally, for clarity or rhythm

With stola, both exist in real usage:

• sa stola (very common)
• s stola (also correct)

The dictionary form is stol (table). stola is genitive singular, required by sa/s in the meaning off/from:

• sa (koga/čega?) stola

So the structure is: sa + genitive.

Croatian word order is fairly flexible, but some orders sound more natural.

Most natural:

• Molim te, pokupi mrvice kruha sa stola.

Also possible (more conversational/emphatic):

• Pokupi, molim te, mrvice kruha sa stola. (with commas, molim te inserted parenthetically)

Without punctuation, moving molim te into the middle can feel cluttered, so writing it with commas helps.
