Travel vocabulary in Croatian centres on putovanje (travel), with the means of transport, documents, and bookings arranged around it. A let (flight) requires a karta (ticket) and involves dealing with prtljaga (luggage) and a rezervacija (reservation). The valuta (currency) you use abroad is part of every transaction, and you might say Let kasni dva sata (The flight is two hours late) or Karta za vlak, molim (A train ticket, please).
Health matters are expressed with the noun zdravlje (health), set against bolest (disease), liječenje (treatment), and lijek (medicine). The place where you receive care is the bolnica (hospital), and the time slot you book is a termin (appointment). A serious situation is a hitan slučaj (emergency), prompting the phrase U hitnom slučaju zovite 112 (In an emergency call 112). The positive outcome of treatment is oporavak (recovery), as in Oporavak je dug ali siguran (Recovery is long but certain), while Zdravlje je najvažnije (Health is the most important thing) is a near-universal slogan.
The natural world is described through priroda (nature) and the okoliš (environment), with klima (climate) shaping both. Environmental concerns are voiced through zagađenje (pollution) and addressed by recikliranje (recycling). Useful sentences include Okoliš trebamo čuvati (We need to protect the environment), Klima se mijenja (The climate is changing), and Recikliranje je obavezno (Recycling is mandatory). Together, this vocabulary lets you discuss journeys, well-being, and ecological responsibility in fluent Croatian.
