Inch (unit)
Measuring tape with inches The inch (symbol: in or ″) is a unit of length in the British imperial and the United States customary systems of measurement. It is equal to yard or of a foot. Derived from the Roman uncia ("twelfth"), the word ''inch'' is also sometimes used to translate similar units in other measurement systems, usually understood as deriving from the width of the human thumb. Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s the inch has been based on the metric system and defined as exactly 25.4 mm. Name The English word "inch" ( ang, ynce) was an early borrowing from Latin ' ("one-twelfth; Roman inch; Roman ounce"). The vowel change from Latin to Old English (which became Modern English ) is known as umlaut. The consonant change from the Latin (spelled ''c'') to English is palatalisation. Both were features of Old English phonology; see and for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Prime
The prime symbol , double prime symbol , triple prime symbol , and quadruple prime symbol are used to designate units and for other purposes in mathematics, science, linguistics and music. Although the characters differ little in appearance from those of the apostrophe and single and double quotation marks, the uses of the prime symbol are quite different. While an apostrophe is now often used in place of the prime, and a double quote in place of the double prime (due to the lack of prime symbols on everyday writing keyboards), such substitutions are not considered appropriate in formal materials or in typesetting. Designation of units The prime symbol is commonly used to represent feet (ft), and the double prime is used to represent inches (in). The triple prime as used in watchmaking represents a ( of a ''French'' inch or '' pouce'', about ). Primes are also used for angles. The prime symbol is used for arcminutes ( of a degree), and the double prime for arcseconds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anglo-Norman Language
Anglo-Norman, also known as Anglo-Norman French ( nrf, Anglo-Normaund) ( French: ), was a dialect of Old Norman French that was used in England and, to a lesser extent, elsewhere in Great Britain and Ireland during the Anglo-Norman period. When William the Conqueror led the Norman conquest of England in 1066, he, his nobles, and many of his followers from Normandy, but also those from northern and western France, spoke a range of langues d'oïl (northern varieties of Gallo-Romance). One of these was Old Norman, also known as "Old Northern French". Other followers spoke varieties of the Picard language or western registers of general Old French. This amalgam developed into the unique insular dialect now known as Anglo-Norman French, which was commonly used for literary and eventually administrative purposes from the 12th until the 15th century. It is difficult to know much about what was actually spoken, as what is known about the dialect is restricted to what was written, but i ...

Middle English
Middle English (abbreviated to ME) is a form of the English language that was spoken after the Norman conquest of 1066, until the late 15th century. The English language underwent distinct variations and developments following the Old English period. Scholarly opinion varies, but the ''Oxford English Dictionary'' specifies the period when Middle English was spoken as being from 1150 to 1500. This stage of the development of the English language roughly followed the High to the Late Middle Ages. Middle English saw significant changes to its vocabulary, grammar, pronunciation, and orthography. Writing conventions during the Middle English period varied widely. Examples of writing from this period that have survived show extensive regional variation. The more standardized Old English language became fragmented, localized, and was, for the most part, being improvised. By the end of the period (about 1470) and aided by the invention of the printing press by Johannes Gutenberg in 14 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ounce

The #International avoirdupois ounce, avoirdupois ounce (exactly ) is Pound (mass)#Avoirdupois pound, avoirdupois pound; this is the United States customary units, United States customary and British imperial unit, imperial ounce. It is primarily used in the United States to measure packaged foods and food portions, postal items, areal density of fabric and paper, boxing gloves, and so on, but it is sometimes also used elsewhere in the Anglosphere. Although the avoirdupois ounce is the mass measure used for most purposes, the 'troy ounce' of exactly is used instead for the mass of precious metals such as gold, silver, platinum, palladium, rhodium, etc. The term 'ounce' is also used in other contexts: * The #Ounce-force, ounce-force is a measure of force (see below). * The fluid ounce is a m ...

Old English Phonology
Old English phonology is necessarily somewhat speculative since Old English is preserved only as a written language. Nevertheless, there is a very large corpus of the language, and the orthography apparently indicates phonological alternations quite faithfully, so it is not difficult to draw certain conclusions about the nature of Old English phonology. Old English had a distinction between short and long (doubled) consonants, at least between vowels (as seen in "sun" and "son", "to put" and "to steal"), and a distinction between short vowels and long vowels in stressed syllables. It had a larger number of vowel qualities in stressed syllables – and in some dialects – than in unstressed ones – . It had diphthongs that no longer exist in Modern English, which were , with both short and long versions. Phonology Consonants The inventory of consonant surface sounds (whether allophones or phonemes) of Old English is as shown below. Allophones are enclosed in par ...

Palatalization (sound Change)
Palatalization is a historical-linguistic sound change that results in a palatalized articulation of a consonant or, in certain cases, a front vowel. Palatalization involves change in the place or manner of articulation of consonants, or the fronting or raising of vowels. In some cases, palatalization involves assimilation or lenition. Types Palatalization is sometimes an example of assimilation. In some cases, it is triggered by a palatal or palatalized consonant or front vowel, but in other cases, it is not conditioned in any way. Consonant Palatalization changes place of articulation or manner of articulation of consonants. It may add palatal secondary articulation or change primary articulation from velar to palatal or alveolar, alveolar to postalveolar. It may also cause a consonant to change its manner of articulation from stop to affricate or fricative. The change in the manner of articulation is a form of lenition. However, the lenition is frequently accompanied ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germanic Umlaut
The Germanic umlaut (sometimes called i-umlaut or i-mutation) is a type of linguistic umlaut in which a back vowel changes to the associated front vowel ( fronting) or a front vowel becomes closer to (raising) when the following syllable contains , , or . It took place separately in various Germanic languages starting around AD 450 or 500 and affected all of the early languages except Gothic. An example of the resulting vowel alternation is the English plural ''foot ~ feet'' (from Proto-Germanic , pl. ). Germanic umlaut, as covered in this article, does not include other historical vowel phenomena that operated in the history of the Germanic languages such as Germanic a-mutation and the various language-specific processes of u-mutation, nor the earlier Indo-European ablaut (''vowel gradation''), which is observable in the conjugation of Germanic strong verbs such as ''sing/sang/sung''.

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Millimetre
330px, Different lengths as in respect to the electromagnetic spectrum, measured by the metre and its derived scales. The microwave is between 1 meter to 1 millimeter. The millimetre (American and British English spelling differences#-re, -er, international spelling; International System of Units, SI unit symbol mm) or millimeter (American and British English spelling differences#-re, -er, American spelling) is a Units of measurement, unit of length in the International System of Units (SI), equal to one thousandth of a metre, which is the SI base unit of length. Therefore, there are one thousand millimetres in a metre. There are ten millimetres in a centimetre. One millimetre is equal to micrometres or nanometres. Since an inch is officially defined as exactly 25.4 millimetres, a millimetre is equal to exactly (≈ 0.03937) of an inch. Definition Since 1983, the metre has been defined as "the length of the path travelled by light in vacuum during a time interval of of a ...
