paragraph_text: Hokkien dialects are analytic; in a sentence, the arrangement of words is important to its meaning. A basic sentence follows the subject–verb–object pattern (i.e. a subject is followed by a verb then by an object), though this order is often violated because Hokkien dialects are topic-prominent. Unlike synthetic languages, seldom do words indicate time, gender and plural by inflection. Instead, these concepts are expressed through adverbs, aspect markers, and grammatical particles, or are deduced from the context. Different particles are added to a sentence to further specify its status or intonation.

paragraph_text: Western Catalan comprises the two dialects of Northwestern Catalan and Valencian; the Eastern block comprises four dialects: Central Catalan, Balearic, Rossellonese, and Alguerese. Each dialect can be further subdivided in several subdialects.

paragraph_text: The Great Vowel Shift was a major series of changes in the pronunciation of the English language that took place primarily between 1350 and the 1600s and 1700s, beginning in southern England, and today having influenced effectively all dialects of English. Through this vowel shift, all Middle English long vowels changed their pronunciation. In addition, some consonant sounds changed as well, particularly those that became silent; the term Great Vowel Shift is sometimes used to include these consonant changes as well.

paragraph_text: In Central Catalan, unstressed vowels reduce to three: /a e ɛ/ > [ə]; /o ɔ u/ > [u]; /i/ remains distinct. The other dialects have different vowel reduction processes (see the section pronunciation of dialects in this article).

paragraph_text: Catalan has inherited the typical vowel system of Vulgar Latin, with seven stressed phonemes: /a ɛ e i ɔ o u/, a common feature in Western Romance, except Spanish. Balearic has also instances of stressed /ə/. Dialects differ in the different degrees of vowel reduction, and the incidence of the pair /ɛ e/.

paragraph_text: Vowel length is not always considered a distinctive feature in Dutch phonology, because it normally co-occurs with changes in vowel quality. One feature or the other may be considered redundant, and some phonemic analyses prefer to treat it as an opposition of tenseness. However, even if not considered part of the phonemic opposition, the long/tense vowels are still realised as phonetically longer than their short counterparts. The changes in vowel quality are also not always the same in all dialects, and in some there may be little difference at all, with length remaining the primary distinguishing feature. And while it is true that older words always pair vowel length with a change in vowel quality, new loanwords have reintroduced phonemic oppositions of length. Compare zonne(n) [ˈzɔnə] ("suns") versus zone [ˈzɔːnə] ("zone") versus zonen [ˈzoːnə(n)] ("sons"), or kroes [krus] ("mug") versus cruise [kruːs] ("cruise").

paragraph_text: The two different historical Estonian languages (sometimes considered dialects), the North and South Estonian languages, are based on the ancestors of modern Estonians' migration into the territory of Estonia in at least two different waves, both groups speaking considerably different Finnic vernaculars. Modern standard Estonian has evolved on the basis of the dialects of Northern Estonia.

paragraph_text: The language possesses five vowels (or six, under the St. Petersburg Phonological School), which are written with different letters depending on whether or not the preceding consonant is palatalized. The consonants typically come in plain vs. palatalized pairs, which are traditionally called hard and soft. (The hard consonants are often velarized, especially before front vowels, as in Irish). The standard language, based on the Moscow dialect, possesses heavy stress and moderate variation in pitch. Stressed vowels are somewhat lengthened, while unstressed vowels tend to be reduced to near-close vowels or an unclear schwa. (See also: vowel reduction in Russian.)

paragraph_text: The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared satellite images. Within the Dvorak satellite strength estimate for tropical cyclones, there are several visual patterns that a cyclone may take on which define the upper and lower bounds on its intensity. The primary patterns used are curved band pattern (T1.0-T4.5), shear pattern (T1.5–T3.5), central dense overcast (CDO) pattern (T2.5–T5.0), central cold cover (CCC) pattern, banding eye pattern (T4.0–T4.5), and eye pattern (T4.5–T8.0).

paragraph_text: Coding refers to the pattern or tones a notification appliance sounds in and is controlled either by the panel or by setting jumpers or DIP switches on the notification appliances. The majority of audible notification appliances installed prior to 1996 produced a steady sound for evacuation. In general, no common standard at that time mandated any particular tone, or pattern for audible fire alarm evacuation signals. While less common than a steady sound, differing signaling methods were used for the same purpose. These are named with respect to their distinctive structure and include, March Time (usually 120 pulses per minute but sometimes at 90 pulses or 20 pulses per minute, depending on the panel), Hi - Lo (two different tones that alternate), Slow - Whoop (slow rising sweep upwards in tone) among others. Today these methods are confined to applications intended to trigger a response other than evacuation alone. In 1996, the ANSI and the NFPA recommended a standard evacuation pattern to eliminate confusion. The pattern is uniform without regard to the sound used. This pattern, which is also used for smoke alarms, is named the Temporal - Three alarm signal, often referred to as ``T - 3 ''(ISO 8201 and ANSI / ASA S3. 41 Temporal Pattern) and produces an interrupted four count (three half second pulses, followed by a one and one half second pause, repeated for a minimum of 180 seconds). CO (carbon monoxide) detectors are specified to use a similar pattern using four pulses of tone (often referred to as T4).

paragraph_text: This can give rise to the situation in which two dialects (defined according to this paradigm) with a somewhat distant genetic relationship are mutually more readily comprehensible than more closely related dialects. In one opinion, this pattern is clearly present among the modern Romance languages, with Italian and Spanish having a high degree of mutual comprehensibility, which neither language shares with French, despite some claiming that both languages are genetically closer to French than to each other:[citation needed] In fact, French-Italian and French-Spanish relative mutual incomprehensibility is due to French having undergone more rapid and more pervasive phonological change than have Spanish and Italian, not to real or imagined distance in genetic relationship. In fact, Italian and French share many more root words in common that do not even appear in Spanish.

paragraph_text: Unique to the development of Dutch is the collaps of older ol/ul/al + dental into ol + dental, followed by vocalisation of pre-consonantal /l/ and after a short vowel, creating the diphthong /ɑu/ e.g., Dutch goud, zout and bout corresponds with Low German Gold, Solt, Bolt; German Gold, Salz, Balt and English gold, salt, bold. This is the most common diphthong along with /ɛi œy/. All three are commonly the only ones considered unique phonemes in Dutch. The tendency for native English speakers is to pronounce Dutch names with /ɛi/ (written as ij or ei) as /aɪ/, (like the English vowel y) which does not normally lead to confusion among native listeners, since in a number of dialects (e.g. in Amsterdam) the same pronunciation is heard.

paragraph_text: In general, Hokkien dialects have 5 to 7 phonemic tones. According to the traditional Chinese system, however, there are 7 to 9 "tones",[citation needed] more correctly termed tone classes since two of them are non-phonemic "entering tones" (see the discussion on Chinese tone). Tone sandhi is extensive. There are minor variations between the Quanzhou and Zhangzhou tone systems. Taiwanese tones follow the patterns of Amoy or Quanzhou, depending on the area of Taiwan. Many dialects have an additional phonemic tone ("tone 9" according to the traditional reckoning), used only in special or foreign loan words.

paragraph_text: A framework was developed in 1967 by Heinz Kloss, abstand and ausbau languages, to describe speech communities, that while unified politically and/or culturally, include multiple dialects which though closely related genetically may be divergent to the point of inter-dialect unintelligibility.

paragraph_text: In Majorcan, unstressed vowels reduce to four: /a e ɛ/ follow the Eastern Catalan reduction pattern; however /o ɔ/ reduce to [o], with /u/ remaining distinct, as in Western Catalan.

paragraph_text: The "Lophotrochozoa" hypothesis is also supported by the fact that many phyla within this group, including annelids, molluscs, nemerteans and flatworms, follow a similar pattern in the fertilized egg's development. When their cells divide after the 4-cell stage, descendants of these 4 cells form a spiral pattern. In these phyla the "fates" of the embryo's cells, in other words the roles their descendants will play in the adult animal, are the same and can be predicted from a very early stage. Hence this development pattern is often described as "spiral determinate cleavage".

paragraph_text: In Western Catalan, unstressed vowels reduce to five: /e ɛ/ > [e]; /o ɔ/ > [o]; /a u i/ remain distinct. This reduction pattern, inherited from Proto-Romance, is also found in Italian and Portuguese. Some Western dialects present further reduction or vowel harmony in some cases.

paragraph_text: Xiamen dialect, sometimes known as Amoy, is the main dialect spoken in the Chinese city of Xiamen and its surrounding regions of Tong'an and Xiang'an, both of which are now included in the Greater Xiamen area. This dialect developed in the late Ming dynasty when Xiamen was increasingly taking over Quanzhou's position as the main port of trade in southeastern China. Quanzhou traders began travelling southwards to Xiamen to carry on their businesses while Zhangzhou peasants began traveling northwards to Xiamen in search of job opportunities. It is at this time when a need for a common language arose. The Quanzhou and Zhangzhou varieties are similar in many ways (as can be seen from the common place of Henan Luoyang where they originated), but due to differences in accents, communication can be a problem. Quanzhou businessmen considered their speech to be the prestige accent and considered Zhangzhou's to be a village dialect. Over the centuries, dialect leveling occurred and the two speeches mixed to produce the Amoy dialect.

paragraph_text: The Estonian dialects are divided into two groups – the northern and southern dialects, historically associated with the cities of Tallinn in the north and Tartu in the south, in addition to a distinct kirderanniku dialect, that of the northeastern coast of Estonia.
