Assimilation is a sound change in which some phonemes (typically consonants or vowels) change to become more similar to other nearby sounds.A common type of phonological process across languages, assimilation can occur either within a word or between words.
For example, /k/ may become /kʷ/ in the environment of /o/, or /a/ may become /o/ in the environment of /p/ or /kʷ/. In the Northwest Caucasian languages as well as some Australian languages rounding has shifted from the vowels to the consonants, producing a wide range of labialized consonants and leaving in some cases only two phonemic vowels.
An example of retained /sk/ is PG *aiskōną > OE ascian > ModE ask; there is evidence that OE ascian was sometimes rendered metathetized to acsian, which is the presumed origin of ModE ask (and also of the modern dialectal pronunciation ax). Palatal diphthongization: Initial palatal /j/, /tʃ/, /ʃ/ trigger spelling changes of a > ea, e > ie. [8]
For example, the English suffix -s is pronounced [s] when it follows a voiceless phoneme (cats), and [z] when it follows a voiced phoneme (dogs). [1] This type of assimilation is called progressive, where the second consonant assimilates to the first; regressive assimilation goes in the opposite direction, as can be seen in have to [hæftə].
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.
In articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators (speech organs such as the tongue, lips, and palate) when making a speech sound. One parameter of manner is stricture, that is, how closely the speech organs approach one another.
The policy of assimilation means in the view of all Australian governments that all aborigines and part-aborigines are expected eventually to attain the same manner of living as other Australians and to live as members of a single Australian community enjoying the same rights and privileges, accepting the same responsibilities, observing the ...
Two or more consonant sounds may appear sequentially linked or clustered as either identical consonants or homorganic consonants that differ slightly in the manner of articulation, as when the first consonant is a fricative and the second is a stop.
