Katakanais a Japanese syllabary, one component of the Japanese writing system along with hiragana, kanji and in some cases the Latin script (known as rōmaji). The word katakana means "fragmentary kana", as the katakana characters are derived from components or fragments of more complex kanji. Katakana and hiragana are both kana systems. With one or two minor exceptions, each syllable (strictly mora) in the Japanese language is represented by one character or kana in each system.
AlphaAlpha 'ælfə (uppercase , lowercase ; ἄλφα, álpha, or álfa) is the first letter of the Greek alphabet. In the system of Greek numerals, it has a value of one. Alpha is derived from the Phoenician letter aleph , which is the West Semitic word for "ox". Letters that arose from alpha include the Latin letter A and the Cyrillic letter А. In Ancient Greek, alpha was pronounced ä and could be either phonemically long ([aː]) or short ([a]). Where there is ambiguity, long and short alpha are sometimes written with a macron and breve today: Ᾱᾱ, Ᾰᾰ.
Minimal pairIn phonology, minimal pairs are pairs of words or phrases in a particular language, spoken or signed, that differ in only one phonological element, such as a phoneme, toneme or chroneme, and have distinct meanings. They are used to demonstrate that two phones represent two separate phonemes in the language. Many phonologists in the middle part of the 20th century had a strong interest in developing techniques for discovering the phonemes of unknown languages, and in some cases, they set up writing systems for the languages.
InterpunctAn interpunct , also known as an interpoint, middle dot, middot, centered dot or centred dot, is a punctuation mark consisting of a vertically centered dot used for interword separation in Classical Latin. (Word-separating spaces did not appear until some time between 600 and 800 CE.) It appears in a variety of uses in some modern languages and is present in Unicode as . The multiplication dot (Unicode ) is frequently used in mathematical and scientific notation, and it may differ in appearance from the interpunct.
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").
Japanese grammarJapanese is an agglutinative, synthetic, mora-timed language with simple phonotactics, a pure vowel system, phonemic vowel and consonant length, and a lexically significant pitch-accent. Word order is normally subject–object–verb with particles marking the grammatical function of words, and sentence structure is topic–comment. Its phrases are exclusively head-final and compound sentences are exclusively left-branching. Sentence-final particles are used to add emotional or emphatic impact, or make questions.
Vowel harmonyIn phonology, vowel harmony is an assimilatory process in which the vowels of a given domain – typically a phonological word – have to be members of the same natural class (thus "in harmony"). Vowel harmony is typically long distance, meaning that the affected vowels do not need to be immediately adjacent, and there can be intervening segments between the affected vowels. Generally one vowel will trigger a shift in other vowels, either progressively or regressively, within the domain, such that the affected vowels match the relevant feature of the trigger vowel.
Laryngeal theoryThe laryngeal theory is a theory in the historical linguistics of the Indo-European languages positing that: The Proto-Indo-European language (PIE) had a series of phonemes beyond those reconstructable by the comparative method. That is, the theory maintains that there were sounds in Proto-Indo-European that no longer exist in any of the daughter languages, and thus, cannot be reconstructed merely by comparing sounds among those daughter languages.
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).
Chain shiftIn historical linguistics, a chain shift is a set of sound changes in which the change in pronunciation of one speech sound (typically, a phoneme) is linked to, and presumably causes, a change in pronunciation of other sounds as well. The sounds involved in a chain shift can be ordered into a "chain" in such a way that after the change is complete, each phoneme ends up sounding like what the phoneme before it in the chain sounded like before the change.
