Length (disambiguation)

Last updated

Length in its basic meaning is the long dimension of an object.

Length is a measure of distance. In the International System of Quantities, length is any quantity with dimension distance. In most systems of measurement, the unit of length is a base unit, from which other units are derived.

Length may also refer to:

Length measurement is implemented in practice in many ways. The most commonly used approaches are the transit-time methods and the interferometer methods based upon the speed of light. For objects such as crystals and diffraction gratings, diffraction is used with X-rays and electron beams. Measurement techniques for three-dimensional structures very small in every dimension use specialized instruments such as ion microscopy coupled with intensive computer modeling.

In phonetics, length or quantity is a feature of sounds that have distinctively extended duration compared with other sounds. There are long vowels as well as long consonants.

In linguistics, vowel length is the perceived duration of a vowel sound. Often the chroneme, or the "longness", acts like a consonant, and may have arisen from one etymologically, such as in Australian English. While not distinctive in most other dialects of English, vowel length is an important phonemic factor in many other languages, for instance in Arabic, Finnish, Fijian, Kannada, Japanese, Old English, Scottish Gaelic and Vietnamese. It plays a phonetic role in the majority of dialects of British English and is said to be phonemic in a few other dialects, such as Australian English, South African English and New Zealand English. It also plays a lesser phonetic role in Cantonese, unlike other varieties of Chinese.

Consonant sound in spoken language, articulated with complete or partial closure of the vocal tract

In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract. Examples are, pronounced with the lips;, pronounced with the front of the tongue;, pronounced with the back of the tongue;, pronounced in the throat; and, pronounced by forcing air through a narrow channel (fricatives); and and, which have air flowing through the nose (nasals). Contrasting with consonants are vowels.

The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin alphabet. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of the sounds of spoken language. The IPA is used by lexicographers, foreign language students and teachers, linguists, speech-language pathologists, singers, actors, constructed language creators and translators.

Manner of articulation configuration and interaction of the articulators when making a speech sound

In articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators when making a speech sound. One parameter of manner is stricture, that is, how closely the speech organs approach one another. Others include those involved in the r-like sounds, and the sibilancy of fricatives.

In 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 are two separate phonemes in the language.

Vocalization or vocalisation may refer to:

Voice or voicing is a term used in phonetics and phonology to characterize speech sounds. Speech sounds can be described as either voiceless or voiced.

In phonetics and phonology, gemination, or consonant lengthening, is an articulation of a consonant for a longer period of time than that of a single instance of the same type of consonant. It is distinct from stress. Gemination literally means "twinning" and comes from the same Latin root as "Gemini".

In linguistics, a chroneme is a basic, theoretical unit of sound that can distinguish words by duration only of a vowel or consonant. The noun chroneme is derived from Greek χρόνος, and the suffixed -eme, which is analogous to the -eme in phoneme or morpheme. However, the term does not have wide currency and may be unknown even to phonologists who work on languages claimed to have chronemes.

In phonetics, clipping is the process of shortening the articulation of a phonetic segment, usually a vowel. A clipped vowel is pronounced more quickly than an unclipped vowel and is often also reduced.

Paicî is the most widely spoken of the two dozen languages on the main island of New Caledonia. It is spoken in a band across the center of the island, from Poindimié to Ponérihouen.

The phonological system of the Polish language is similar in many ways to those of other Slavic languages, although there are some characteristic features found in only a few other languages of the family, such as contrasting retroflex and palatal fricatives and affricates, and nasal vowels. The vowel system is relatively simple, with just six oral monophthongs and two nasals, while the consonant system is much more complex.

In phonetics and historical linguistics, fusion, or coalescence, is the merger of features from two or more segments into a single segment.

Jalapa Mazatec is a Mazatecan language, as of 1990 spoken by ca. 15,000 people, one-third of whom are monolingual, in 13 villages in the vicinity of the town of San Felipe Jalapa de Díaz in the Tuxtepec District of the Mexican state of Oaxaca. Egland (1978) found 73% intelligibility with Huautla, the prestige variety of Mazatec. Literacy in Jalapa is taught alongside Spanish in local schools.

Ndrumbea, variously spelled Ndumbea, Dubea, Drubea and Païta, is a New Caledonian language that gave its name to the capital of New Caledonia, Nouméa, and the neighboring town of Dumbéa. It has been displaced to villages outside the capital, with fewer than a thousand speakers remaining. Gordon (1995) estimates that there may only be two or three hundred. The Dubea are the people; the language has been called Naa Dubea "language of Dubea".
