Literally, lončarska radionica means potter’s workshop or pottery workshop.

• lončar = potter
• lončarski / lončarska / lončarsko = pottery-related, potter’s

Because lončarska has to agree with radionica.

In Croatian, adjectives change form to match the noun’s:

• gender
• number
• case

Here, radionica is:

• feminine
• singular
• nominative

So the adjective must also be feminine singular nominative:

• masculine: lončarski
• feminine: lončarska
• neuter: lončarsko

Radionica is feminine.

A useful clue is that many Croatian nouns ending in -a are feminine, including radionica. Because it is feminine, the adjective before it becomes lončarska.

Počinje is the 3rd person singular present tense of the verb počinjati / početi meaning to begin / to start.

It matches the subject lončarska radionica, which is singular:

• radionica počinje = the workshop begins / starts

So the grammar is:

• lončarska radionica = subject
• počinje = verb
• danas = today

Croatian often uses the present tense for a scheduled or near-future event, just like English can do.

So Lončarska radionica počinje danas can mean:

• The pottery workshop starts today
• The pottery workshop is starting today

This is very natural in Croatian for timetables, events, lessons, courses, and similar planned things.

Yes. The verb agrees with the noun that is the subject, which is radionica.

Lončarska is only an adjective describing the noun. It does not control the verb.

So:

• radionica počinje = singular
• if the subject were plural, the verb would be plural too

For example:

• Lončarske radionice počinju danas = Pottery workshops start today

Lončarska radionica is in the nominative case, because it is the subject of the sentence.

• lončarska = feminine singular nominative
• radionica = feminine singular nominative

Danas is an adverb, so it does not change for case.

Yes. Croatian word order is more flexible than English word order.

The neutral order here is:

• Lončarska radionica počinje danas.

But you could also say:

• Danas počinje lončarska radionica.
• Počinje danas lončarska radionica.

These alternatives may change the emphasis:

• Danas first emphasizes today
• the original version sounds neutral and straightforward

Croatian has no articles, so there is no word corresponding directly to the or a/an.

So Lončarska radionica počinje danas can mean:

• The pottery workshop starts today
• A pottery workshop starts today

The exact meaning depends on context.

The letter č is pronounced roughly like ch in chocolate, but usually a bit firmer.

So:

• lončarska ≈ lon-char-ska
• počinje ≈ po-chin-ye

A few pronunciation notes:

• č = a hard ch sound
• nj in počinje sounds like the ny in canyon
• final -je is pronounced clearly, not silent

Not always. Radionica can mean:

• a workshop as an organized learning session
• a hands-on class
• sometimes a studio/workshop space, depending on context

In this sentence, it most likely means an organized pottery workshop/class, not necessarily just the physical room.

Sometimes, but the meaning changes slightly.

• radionica = workshop, usually practical and interactive
• tečaj = course
• kurs = course, also used but often less neutral or more regional/context-dependent

So if you mean a hands-on pottery session, radionica is probably the best choice.

The sentence follows a simple pattern:

• Subject: Lončarska radionica
• Verb: počinje
• Time expression: danas

So the structure is:

[subject] + [verb] + [time]

This is one of the most common and useful sentence patterns in Croatian.
