Different types of assimilation

Different types of assimilation

1. affecting the direction;

2. affecting the place of obstruction;

3. affecting the position of the lips;

4. affecting the work of vocal cords;

5. affecting the manner of noise production.

1) is divided into progressive, regressive and reciprocal (double).

2) [t], [d], [n], [l] + [θ], [ð] = apical-alveolar sounds [t], [d], [n], [l] become dental under the influence of interdental [θ], [ð] which follow:

e.g. [in___ ðə], [ðæt___θi:m]

3) [t], [d], [k], [g], [s] + sonant [w] = [t], [d], [k], [g], [s] become labialized:

e.g. [kwait], [dwel], [gwen], [swon], [twelv]

4) voiced + voiceless consonants;

voiceless consonants + sonant + vowel = sonants [m], [n], [l], [r], [j], [w] become partly voiceless:

e.g. [plei], [trai], [twelve] – partial progressive assimilation affecting the work of the vocal cords while pronouncing sonants [l], [r], [w].

5) the phenomenon may be described with the aid of the terms:

· nasal plosion – while pronouncing [pm], [tn]: [b tn], [peid__m ni].

· lateral plosion – [p], [b], [t], [d], [k], [g] + [l]: [plæn], [gυd__lυks].

· fricative plosion - [p], [b], [t], [d], [k], [g] + [s], [z]: [stops]

Loss of plosion or incomplete plosion may be observed in clusters of 2 plosive consonants of the same or different articulation: [pp], [pb], [tt], [td], [kk], [kg], [kt], [dg], [db], [tb] or clusters of a plosive and an affricate [t∫], [dg]:

[stop___po:riŋ], [dig___graund], [‘ækt∫uəli].

Mixed types of assimilation:

1) [tri:], [put___rait] – assimilation affecting the place of obstruction + assimilation affecting the work of the vocal + assimilation affecting the manner of noise production.

2) [mi:t___w ns] – assimilation affecting the position of the lips + assimilation affecting the work of vocal cords.
