Compound nouns (-o-)

Building with Words

Croatian frequently creates new nouns by joining two existing words. To make the new compound word flow smoothly, the two parts are connected by a linking vowel, most commonly -o-.

Take brod (ship) and gradilište (building site). Join them with -o-, and you get brodogradilište (shipyard).

There is no old shipyard in this city anymore.
U ovom gradu više nema starog brodogradilišta.

Similarly, combining brod and vlasnik (owner) gives you brodovlasnik.

The shipowner went to the shipyard yesterday.
Brodovlasnik je jučer otišao u brodogradilište.

Replacing Final Vowels

When the first word ends in a consonant, you simply add the -o- after it. But if the first word already ends in a vowel (like the feminine noun riba, meaning fish), you drop that final vowel and replace it with -o-.

So, brod + gradnja (construction) becomes brodogradnja. And riba + lov (hunt) becomes ribolov (fishing).

This city lives from shipbuilding and fishing.
Ovaj grad živi od brodogradnje i ribolova.

Here is ribolov used as the subject of the sentence:

In winter, fishing is often dangerous.
Zimi je ribolov često opasan.

Maritime Disasters and Innovations

This pattern applies to many concepts relating to the sea. Joining brod with lom (break or fracture) creates brodolom (shipwreck).

Several sailors survived the shipwreck.
Nekoliko mornara je preživjelo brodolom.

If the first word is para (steam), you drop the final -a and add the linking -o- before brod to get parobrod (steamboat).

We saw a steamboat that was sailing toward the island.
Vidjeli smo parobrod koji je plovio prema otoku.

Trade and Tides

Verbs and their noun derivatives can also form compounds. Joining the concepts of buying (kupiti) and selling (prodaja) yields kupoprodaja (trade, or buying and selling).

The trade will be finished next week.
Kupoprodaja će biti gotova sljedeći tjedan.

Returning to nature, joining voda (water) with the root for standing gives us vodostaj (water level).

A low water level makes work in the port difficult.
Nizak vodostaj otežava posao u luci.

Compass Directions

Finally, compound nouns are the standard way to express intermediate compass directions. You simply join two cardinal directions with -o-.

For example, jug (south) and zapad (west) become jugozapad.

A strong wind is blowing in the southwest.
Jak vjetar puše na jugozapadu.

Likewise, sjever (north) and istok (east) form sjeveroistok.

We were watching the black clouds in the northeast.
Gledali smo crne oblake na sjeveroistoku.
