In the first sense, it refers to any type of long distance assimilatory process of vowels, either progressive or regressive.
Van der Hulst & van de Weijer (1995) point to two such situations: polysyllabic trigger morphemes may contain non-neutral vowels from opposite harmonic sets and certain target morphemes simply fail to harmonize.
In modern Korean, it is only applied in certain cases such as onomatopoeia, adjectives, adverbs, conjugation, and interjections.
Some sources refer to the primary harmonization dimension as pharyngealization or palatalness (among others), but neither of these is technically correct.
Likewise, referring to ±RTR as the sole defining feature of vowel categories in Mongolian is not fully accurate either.
In any case, the two vowel categories differ primarily with regards to tongue root position, and ±RTR is a convenient and fairly accurate descriptor for the articulatory parameters involved.
Therefore, most grammatical suffixes come in front and back forms, e.g. Türkiye'de "in Turkey" but Almanya'da "in Germany".
This gives constructions such as Türkiye'dir "it is Turkey", kapıdır "it is the door", but gündür "it is the day", karpuzdur "it is the watermelon".
In the suffix -(i)yor, the o is invariant, while the i changes according to the preceding vowel; for example sönüyor – "he/she/it fades".
There are also a few native modern Turkish words that do not follow the rule (such as anne "mother" or kardeş "sibling" which used to obey vowel harmony in their older forms, ana and karındaş, respectively).
However, in such words, suffixes nevertheless harmonize with the final vowel; thus annesi – "his/her mother", and voleybolcu – "volleyballer".
Disharmony tends to disappear through analogy, especially within loanwords; e.g. Hüsnü (a man's name) < earlier Hüsni, from Arabic husnî; Müslüman "Moslem, Muslim (adj.
[11] Persian is a language which includes various types of regressive and progressive vowel harmony in different words and expressions.
Vowel harmony is often hypothesized to have existed in Proto-Uralic, though its original scope remains a matter of discussion.
Single-vowel words which have only the neutral vowels (i, í or é) are unpredictable, but e takes a front-vowel suffix.
Some other rules and guidelines to consider: Grammatical suffixes in Hungarian can have one, two, three, or four forms: An example on basic numerals: Vowel harmony occurred in Southern Mansi.
In the Khanty language, vowel harmony occurs in the Eastern dialects, and affects both inflectional and derivational suffixes.
It has been lost in Livonian and in Standard Estonian, where the front vowels ü ä ö occur only in the first (stressed) syllable.
For example, standard 'ie' is reflected as 'ia' or 'iä', controlled by noninitial syllables, in the Tampere dialect, e.g. tiä ← tie but miakka ← miekka ... as evidenced by tuotteessa (not *tuotteessä).
As a consequence, Finnish speakers often have problems with pronouncing foreign words which do not obey vowel harmony.
The position of some loans is unstandardized (e.g. chattailla/chättäillä) or ill-standardized (e.g. polymeeri, sometimes pronounced polumeeri, and autoritäärinen, which violate vowel harmony).
For example, syyskuu ("autumn month" i.e. September) has both u and y, but it consists of two words syys and kuu, and declines syys·kuu·ta (not *syyskuutä).
The same goes for enclitics, e.g. taaksepäin "backwards" consists of the word taakse "to back" and -päin "-wards", which gives e.g. taaksepäinkään (not *taaksepäinkaan or *taaksepainkaan).
If fusion takes place, the vowel is harmonized by some speakers, e.g. tälläinen pro tällainen ← tämän lainen.
Examples include meri "sea", meressä "in the sea" (inessive), but merta (partitive), not *mertä; veri "blood", verestä "from the blood" (elative), but verta (partitive), not *vertä; pelätä "to be afraid", but pelko "fear", not *pelkö; kipu "pain", but kipeä "sore", not *kipea.
For example, অনুবাদ ( onubad )( translation ) and অনেক (ɔnek) ( many) begin with the same letter being pronounced differently due to the presence of 'u' after 'o' in the first one.
Similarly, in the absence of any diacritic marks on any consonant letter, its default vowel is 'ɔ' or 'o' using the same rule.
If flat consonants do not occur in a word, then all vowels will be of the non-flat class: Other languages of this region of North America (the Plateau culture area), such as St'át'imcets, have similar vowel–consonant harmonic processes.
This rule remained in place for a long time, and ensured that a syllable containing a front vowel always began with a palatal consonant, and a syllable containing j was always preceded by a palatal consonant and followed by a front vowel.
[28] Languages such as Nez Perce and Chukchi have vowel harmony systems which can not be easily explained in terms of height, backness, tongue root, or rounding.
