Yapese language in the context of "Chuukic languages"

Native languages of Oceania fall into three major geographic groups:

• The large Austronesian language family, with such languages as Malay (Indonesian), Tagalog (Filipino), and Polynesian languages such as Māori and Hawaiian
• The various Aboriginal Australian language families, including the large Pama–Nyungan family
• The various Papuan language families of New Guinea and neighbouring islands, including the large Trans–New Guinea family

Contact between Austronesian and Papuan resulted in several instances in mixed languages such as Maisin.

Yap (Yapese: Waqab, sometimes written as Wa'ab, Waab or Waqaab) traditionally refers to an island group located in the Caroline Islands of the western Pacific Ocean, a part of Yap State. The name "Yap" in recent years has come to also refer to the state within the Federated States of Micronesia, inclusive of the Yap Main Islands and its various outer islands, the Yap Neighboring Islands. For specifying the island group, the name Yap Main Islands is most exact.

Ulithi (Yapese: Wulthiy, Yulthiy, or Wugöy; pronounced roughly as YOU-li-thee) is an atoll in the Caroline Islands of the western Pacific Ocean, about 191 km (103 nmi) east of Yap, within Yap State.

A rai stone (Yapese: raay), or fei stone, is one of many large artifacts that were manufactured and treasured by the native inhabitants of the Yap islands in Micronesia. They are also known as Yapese stone money or similar names.

The typical rai stone is carved out of crystalline limestone and shaped like a disk with a hole in the center. The smallest may be 3.5 centimetres (1.4 in) in diameter. The largest extant stone is located on Rumung island, near the Riy village; it is 3.6 metres (12 ft) in diameter and 50 centimetres (20 in) thick, and weighs 4,000 kilograms (8,800 lb).

The Admiralty Islands languages are a group of some thirty Oceanic languages spoken on the Admiralty Islands. They may include Yapese, which has proven difficult to classify.

Nguluwan is a mixed language spoken on Ngulu Atoll located between Yap and Palau. The grammar and lexicon are Yapese, but the phonology has been affected by Ulithian. This language is endangered as it only has 50 speakers and that its speakers are shifting to Ulithian.

Gagil (Yapese: Gagil, dialect Ggil) is a municipality in the state of Yap, in the Federated States of Micronesia. It forms part of Gagil-Tamil (it) Island and covers the eastern side of the island. It has a population of roughly 400 people scattered in village groups. One of these villages includes the village of Gachpar which was once the capital of the historic Yap Islands Empire that lasted from about 10th to the 15th century AD and stretched as far as east as the west halls of Chuuk Lagoon, as far south as the northern atolls of Papua New Guinea, and as far west as the outer islands of Palau.
