EtaEta 'iːtə,_'eɪtə (uppercase , lowercase ; ἦτα ē̂ta ɛ̂ːta or ήτα ita ˈita) is the seventh letter of the Greek alphabet, representing the close front unrounded vowel i. Originally denoting the voiceless glottal fricative h in most dialects, its sound value in the classical Attic dialect of Ancient Greek was a long open-mid front unrounded vowel ɛː, raised to i in hellenistic Greek, a process known as iotacism or itacism.
OmegaOmega (oʊˈmiːɡə,_oʊˈmɛɡə,_oʊˈmeɪɡə,_əˈmiːɡə; capital: Ω, lowercase: ω; Ancient Greek ὦ, later ὦ μέγα, Modern Greek ωμέγα) is the twenty-fourth and final letter in the Greek alphabet. In the Greek numeric system/isopsephy (gematria), it has a value of 800. The word literally means "great O" (ō mega, mega meaning "great"), as opposed to omicron, which means "little O" (o mikron, micron meaning "little").
Romanization of JapaneseThe romanization of Japanese is the use of Latin script to write the Japanese language. This method of writing is sometimes referred to in Japanese as ローマ字. Japanese is normally written in a combination of logographic characters borrowed from Chinese (kanji) and syllabic scripts (kana) that also ultimately derive from Chinese characters. There are several different romanization systems. The three main ones are Hepburn romanization, Kunrei-shiki romanization (ISO 3602) and Nihon-shiki romanization (ISO 3602 Strict).
Umlaut (diacritic)The umlaut (ˈʊmlaʊt) is the diacritical mark used to indicate in writing (as part of the letters , , and ) the result of the historical sound shift due to which former back vowels are now pronounced as front vowels (for example a, ɔ, and ʊ as ɛ, œ, and ʏ). (The term [Germanic] umlaut is also used for the underlying historical sound shift process.) In its contemporary printed form, the mark consists of two dots placed over the letter to represent the changed vowel sound.
EpsilonEpsilon (ˈɛpsᵻlɒn, UKalsoɛpˈsaɪlən; uppercase Ε, lowercase ε or lunate ε; έψιλον) is the fifth letter of the Greek alphabet, corresponding phonetically to a mid front unrounded vowel e̞ or ɛ̝. In the system of Greek numerals it also has the value five. It was derived from the Phoenician letter He . Letters that arose from epsilon include the Roman E, Ë and Ɛ, and Cyrillic Е, È, Ё, Є and Э.
Hepburn romanizationHepburn romanization is the main system of romanization for the Japanese language. The system was originally published in 1867 by American Christian missionary and physician James Curtis Hepburn as the standard in the first edition of his Japanese–English dictionary. The system is distinct from other romanization methods in its use of English orthography to phonetically transcribe sounds: for example, the syllable ɕi (し) is written as hepburn and tɕa (ちゃ) is written as hepburn, reflecting their spellings in English (compare to nihon-shiki and tya in the more-systematic Nihon-shiki and Kunrei-shiki systems).
Tongan languageTongan (English pronunciation: ˈtɒŋən or ˈtɒŋɡən; lea fakatonga) is an Austronesian language of the Polynesian branch native to the island nation of Tonga. It has around 187,000 speakers. It uses the word order verb–subject–object. Tongan is one of the multiple languages in the Polynesian branch of the Austronesian languages, along with Hawaiian, Māori, Samoan and Tahitian, for example. Together with Niuean, it forms the Tongic subgroup of Polynesian. Tongan is unusual among Polynesian languages in that it has a so-called definitive accent.
