Papua New Guinea is the most linguistically diverse country in the world, boasting over 800 distinct languages spoken within its borders. This impressive linguistic variety is a result of the country's complex geography, with rugged mountains, dense forests, and isolated communities fostering the development of unique languages over centuries.

The languages belong to several different language families, the largest being the Trans-New Guinea family. While Tok Pisin, English, and Hiri Motu serve as official languages for communication and governance, the rich tapestry of indigenous languages highlights Papua New Guinea's remarkable cultural and linguistic heritage.
