The Nauruan or Nauru language is an Austronesian language that is spoken exclusively on the island of Nauru. There is no adequate written grammar of the language, and its relationships to other Micronesian languages are unclear. English is widely understood. Nauru is regarded as one of the most Westernized South Pacific countries. This is one of Unique Cultural Characteristics In Nauru that you should know.

According to a report published in Sydney in 1937, there was a variety of dialects until Nauru became a German colony in 1888, and until the publication of the first texts written in Nauruan. The varieties were so diverse that people from different districts frequently had difficulty understanding each other completely. With the growing influence of foreign languages and the proliferation of Nauruan texts, the dialects merged into a standardized language, which Alois Kayser and Philip Delaporte promoted through dictionaries and translations. Today, dialectal variation is significantly reduced. There is an eponymous dialect spoken in Yaren and the surrounding area, which is only slightly different.

Philip Delaporte published his pocket German-Nauruan dictionary in 1907. The dictionary is small (10.5 14 cm), with 65 pages dedicated to the glossary and another dozen to phrases, which are organized alphabetically by German. In Nauruan, approximately 1650 German words are glossed, often by phrases or synonymous forms. The glosses contain approximately 1300 'unique' Nauruan forms, including all those occurring in phrases, ignoring diacritical marks. The accents used there are uncommon; only one accent (the tilde) is currently in use.

The majority religion in Nauru is Christianity, with the Nauru Congregational Church being the largest denomination, accounting for 35.71% of the population as of the 2011 census. Religion freedom is a constitutional right, and the country's laws and society uphold it without significant violations.

According to the 2002 census, roughly two-thirds of Christians are Protestant, with the remainder being Catholic. The Nauru Congregational Church is the largest denomination. The ethnic Chinese on the island, who make up about 3 to 4% of the population, may be Confucian, Buddhist, Taoist, Christian, or atheist. Following the near-cease of phosphate mining in the country, the largely Christian communities of Tuvaluan and I-Kiribati expatriates were repatriated in late 2006.

Prior to the late nineteenth and early twentieth centuries, when foreign missionaries introduced Christianity to the island, Nauruan indigenous religion was the dominant religion on the island. There are a few active Christian missionary organizations, including Anglican, Methodist, and Catholic representatives.

The constitution of Nauru guarantees freedom of conscience and expression, but it also states that these rights may be restricted by any law that is "reasonably required." To proselytize, build houses of worship, hold religious services, or officiate marriages, religious groups must register with the government. Private schools run by religious organizations are permitted. Religious groups are permitted to offer religious studies classes once a week during school hours in public schools. There are no significant societal constraints on religious freedom in Nauru, according to a 2017 US government report.

The people of Nauru dress in typical tropical attire: shorts and light shirts. Fishing is still done in the traditional way, with island anglers waiting in small light boats for fish to arrive. The tradition of fishing with trained frigatebirds has survived. Radio Nauru has a large collection of recordings of local people's music. Even elderly Nauruans, however, rarely understand the lyrics to these songs. Nauru's music reflects its Micronesian heritage. "Nauru Bwiema" is the national anthem of Nauru ("Song of Nauru"). The lyrics were written by Margaret Hendrie, and the music was composed by Laurence Henry Hicks.

While traditional culture is quickly giving way to contemporary culture in Micronesia, music and dance remain among the most popular art forms. Rhythmic singing and traditional reigen are especially performed at celebrations, and craftsmen make articles of clothing and fans out of Kokosfasern and screw tree sheets, using geometrical samples similar to those found in Indonesian culture. The wood of the kokospalme is also used in the production of arts and crafts. This things can be seen as one of Unique Cultural Characteristics In Nauru.

Australian rules football is the most popular in Nauru. The country has a 12-team senior league, see Australian rules football in Nauru, and it is a popular spectator sport. Nauru has represented Australia at the Arafura Games, the Australian Football International Cup, and the Barassi International Youth Tournament. The national team, known as the "Chiefs," finished eighth in the International Cup in 2002 and won gold at the Arafura Games. Nauru's national basketball team made international headlines in 1969 when it defeated the Solomon Islands, which have nearly 60 times the population of Nauru, and Fiji, which has nearly 100 times the population of Nauru.

Nauruans also enjoy sports such as soccer, softball, tennis, sailing, swimming, and golf. Nauru has only a few sports grounds. Yaren has the only stadium, but it is outdated and does not meet international standards. A larger and more modern sports stadium is being built in Meneng, but the project has been halted due to a lack of funds.

Catching birds (Black Noddy) as they return from foraging at sea to the island near sunset is a traditional 'sport.' The men then prepare to throw their lasso on the beach. The Nauruan lasso is a flexible rope with a weight attached at one end. When a bird comes over, they throw their lasso up, hit or drape themselves over the bird, which then falls down and is seized and roosted as a pet.

It can be considered as one of Unique Cultural Characteristics In Nauru. All Nauruans are members of a matrilineal group or clan. In a public document, each birth and death is identified by clan affiliation. That affiliation lasts the lifetime of the individual and is not altered by marriage. A marriage partner must be chosen from a different clan. Marriage is largely a Christian institution today, though there are concerns that some young people are choosing not to marry; their children are descended from the mother's lineage. Households revolve around the mother, who cares for and is cared for by her children.

The male is the nominal head of the household, but the mother is the decision-making head, and she is primarily responsible for economic management as well as social care. Both sons and daughters inherit land and other properties, but only daughters can pass on their rights to their children without seeking extended family consent. Modern possessions, such as motorcycles, are passed down through extended families. Every Nauruan is assigned to a district. That affiliation is inherited from one's mother or father, but it can be changed during one's lifetime for political reasons. Participation in district activities is a requirement of district affiliation.
