The plural noun endings in the instrumental are identical to those in the dative and locative, and the rules on when to use the instrumental are very straightforward.
The instrumental case is most commonly used in three different situations:
When is the instrumental case used in Croatian?
To denote the tool or means used to accomplish an action
i.e. when referring to the instrument being used, hence the name!
Idem na posao autobusom. – I travel to work by bus.
To state company (similar to with in English)
i.e. who we’re doing something with
Idem u kino s mamom. – I’m going to the cinema with my mom.
To refer to the unity of two entities
i.e. when referring to one thing combined with another
Pijem kavu s mlijekom. – I’m drinking a coffee with milk.

Instrumental without prepositions
You probably noticed that two of these sentences above use the preposition and one doesn’t. When the instrumental is used in the context of explaining a tool or the means used to accomplish an action, there’s no preposition necessary.
- Pišem olovkom. – I’m writing with a pencil.
- Putujem zrakoplovom. – I’m travelling by plane.
- Jedem štapićima. – I’m eating with chopsticks.
Instrumental with prepositions
The instrumental case is used with several prepositions, but the most common is s (meaning “with”) or its variation sa which is used when the following word begin with letters s, š, z or ž. The prepositions s and sa are used when:
Talking about company:
- Putujem s Majom. – I’m travelling with Maja.
- Idem na posao s mužem. – I’m going to work with my husband.
- Igram tenis sa ženom. – I’m playing tennis with my wife.
Talking about the unity of two entities:
- Jedem sendvič sa šunkom i sirom. – I’m eating a sandwich with ham and cheese.
- Gledam ženu sa šeširom. – I’m watching the woman with a hat.
- Volim jagode sa šlagom. – I like strawberries with cream.
The preposition s is always pronounced as one with the following word, e.g. smamom (s mamom), smužem (smužem).
If you find these rules about then to and when not to use the preposition s confusing, don’t worry! Most Croatians find them confusing too, and many people use the same preposition in all three situations ...
