18. Classificatory principles of English consonants as the basis for the phonological oppositions in the system of English consonant phonemes.

Classificatory principles of English consonants as the basis for the phonological oppositions in the system of English consonant phonemes.

English consonants are classified according to the following principles:

  1. Work of the vocal cords and the force of exhalation.

According to the work of the vocal cords and the force of exhalation English consonants are subdivided into voiced and voiceless. Voiced consonants are produced with the vocal cords brought together and vibrating. They are [b, d, g, v, z, ð, 3, d3, l, m, n, j, w, r, ŋ]. Voiceless consonants are produced with the vocal cords taken apart and not vibrating. They are [p, t, k, f, s, θ, ∫, t∫, h]. The force of exhalation and the degree of muscular tension are greater in the production of voiceless consonants.

  1. Active organ of speech and the place of obstruction

According to the position of the active organ of speech against the place of obstruction English consonants are classified into labial, lingual and glottal.

Labial consonants are subdivided into bilabial and labiodental. Bilabial consonants are articulated with both lips. They are [p, b, w, m]. Labiodental consonants are articulated with the lower lip against the edge of the upper teeth. They are [f, v].

Lingual consonants are subdivided into forelingual, mediolingual and backlingual.

Forelingual consonants are articulated with the tip or the blade of the tongue. According to the place of obstruction English forelingual consonants are subdivided into interdental, alveolar, post-alveolar and palato-alveolar. Interdental consonants are articulated with the tip of the tongue projected between the teeth. The are [ð, θ]. Alveolar consonants are articulated with the tip of the tongue against the upper teeth ridge. They are [t, d, s, z, l, n]. Post alveolar consonants are articulated with the tip or the blade of the tongue against the back part of the teeth ridge. In English it is [r]. Palato-alveolar consonants are articulated with the tip or the blade of the tongue against the teeth ridge, the front part of the tongue raised towards the hard palate. They have two places of articulation. They are [∫, 3, d3, t∫].

Mediolingual consonants are articulated with the front part of the tongue raised high to the hard palate. In English it is [j].

Backlingual consonants are articulated with the back part of the tongue raised towards the soft palate. They are [k, g, ŋ].

Glottal (pharyngeal) consonants are articulated in the glottis. In English it is [h].

  1. Manner of the noise production and the type of obstruction.

According to the type of obstruction consonants are divided into occlusive, constrictive and occlusive-constrictive or affricates. Occlusive consonants are articulated with the air on its way out breaking up a complete obstruction. In English occlusive consonants are subdivided into plosives [p, t, k, b, d, g] which are articulated with distinct and quick separation of the obstruction and sonorants [m, n, ŋ]. Constrictive consonants are articulated with incomplete obstruction through which the air comes out. In English constrictive consonants are subdivided into fricatives [s, f, z, ð, θ, ∫, v, 3, h] which are articulated with the air passage narrowed to such an extent that the air passing through it produces friction, and sonorants [w, r, j, l] which are articulated with the air passage wide enough to make the cavity function as a resonator. Occlusive-constrictive consonants are articulated with the complete obstruction gradually and uninterruptedly opening into narrowing. In English they are [t∫, d3].

  1. Position of the soft palate.

According to the position of the soft palate consonants are subdivided into oral and nasal. Nasal consonants are articulated with the blocked passage for the flow of air through the mouth cavity which is effected by lowering of the soft palate. They are [m, n, ŋ]. All the rest consonants are oral. Oral consonants are articulated with the raised soft-palate, thus the air goes out through the mouth cavity.

Phonological oppositions in the system of English vowel and consonant phonemes.

Classificatory principles of English vowel and consonant phonemes provide the basis for establishing the distinctive oppositions.

Distinctive oppositions of English consonants

Classificatory principles and subclasses of phonemes

Types of oppositions

Examples

1. Work of the vocal cords:

- voiced [b, d, g, v, z, ð, 3, d3, l, m, n, j, w, r, ŋ];

- voiceless [p, t, k, f, s, θ, ∫, t∫, h].

voiced – voiceless

The English consonants [l, m, n, j, w, r, ŋ, h] do not enter this opposition.

gum – come

dear – tear

bat – pat

jin – chin

thy – thigh

2. Position of the soft palate:

- nasal [m, n, ŋ];

- oral (all the rest).

oral – nasal

pit – pin

seek – seen

sick – sing

3. Active organ of speech and the place of articulation:

a) labial:

- bilabial [p, b, w, m];

- labio-dental [f, v];

b) lingual:

- forelingual [ð, θ, t, d, s, z, n, l, ∫, 3, d3, t∫];

- mediolingual [j];

- backlingual [k, g, ŋ];

c) glottal [h].

labial – lingual

lingual – glottal

labial – glottal

bilabial – labio-dental

forelingual – mediolingual

forelingual – backlingual

mediolingual – backlingual

pain – cane

this – hiss

foam – home

wear – fair

jet – yet

thing – king

yes – guess

4. Manner of the production of noise:

a) occlusive:

- plosive

[p, t, k, b, d, g]

- sonorant [m, n, ŋ];

b) constrictive:

- fricative [s, f, z, ð, θ, ∫, v, 3, h];

- sonorant [w, r, j, l];

c) occlusive-constrictive (affricates) [t∫, d3].

occlusive – constrictive

affricate – constrictive

affricate – occlusive

occlusive: plosive – sonorant

constrictive: fricative – sonorant

bat – that

fair – chair

chin – pin

pine – mine

same – lame
