Examples of open and close syllabic junctures:

Open juncture a nice house // a nation / / Joy sleeps // I scream! / / I saw her race /  / that stuff the waiter cut it pets enter stopped aching

Close juncture an ice-house / / an Asian / / Joyce leaps / / Ice cream / / I saw her ace /   / that’s tough the way to cut it Pets centre Stop taking

The phonetic nature of open juncture is complex. Its occurrence involves changes in length, pitch, aspiration and in other features of sounds, e.g.: in the pair of words ni^|trate – night-^|rate the distinction in juncture lies in: 1) the greater degree of aspiration of /t/ in the first word; 2) allophonic difference of /r/ – in the first member of the opposition it is slightly devoiced under the influence of the initial /t/; 3) the diphthong // is shorter in the second word because the syllable is closed by a voiceless /t/, etc.

Phonotactics is the branch of phonology that studies the characteristics of sounds and sound sequences and the rules according to which sounds are combined in connected speech in a certain language. Phoneme sequences are at best described in terms of clustering habits. A cluster is a sequence of two or more phonemes of the same class without an intervention of a phoneme of another class. As is known languages do not allow phonemes to appear in any order. According to their position in the phonetic structure of a word clusters can be divided into: 1) prevocalic, 2) post-vocalic and 3) intervocalic. In English prevocalic clusters, the largest number of consonants is three:

/spl/ – splash /spr/ – spray /spj/ – spume

/str/ – straw /stj/ – student

/skl/ – sklent /skr/ – scream /skj/ – skewer /skw/ – square.

The clusters /spl/, /spr/, /str/, /skw/ are used most frequently, the others less so.

Certain initial and final clusters are sometimes associated with particular feelings or human characteristics. E.g. such initial clusters as: 1) /sl-/: sly, slick, slothful, sluggard, sluggish, sloppy, slipshod, slime, slither, slug, etc, /sn-/: sniff, sneer, snigger, snitch, sneak, snivel, snob, snotty, snide, sniffle, /kr-/: crash, crack evoke, as a rule, unpleasant associations; 2) /fl-/ associates with quick and light movement: fly, flash, flame, flap, flip, flee, flit; 3) /gl-/ associates with: a) static (unmoveable) light, e.g.: glow, glimmer, glare, gloat; b) obscure light, e.g.: gleam, glitter, glisten, c) dusky light, e.g.: gloaming; 3) /tr-/ associates with speed; 4) /gr-/ associates with grumbling; 5) /br-/ is associated with noise and mess, etc.

Final consonantal clusters, for instance, 1) /-mp/ associates with awkwardness and clumsiness as well as with large blunt shapes, e.g.: bump, lump, hump, rump, mump(s), clump; 2) a whole family of such words as muddle, fumble, straddle, cuddle, fiddle, buckle (v), struggle, wriggle are associated with clumsy, awkward or difficult action because they all end with a plosive and a syllabic //.

As is known languages do not allow phonemes to appear in any order. It is the feature of English that 1) vowels /, , , , , , , , , , , , , , , , , , / almost always constitute the peaks of prominence; 2) speech sound // never occurs in stressed syllables, the vowel / / very often occurs in unstressed syllables; 3) long vowels and diphthongs do not precede final //, sounds /   / never occur finally. As to the consonants, one can come across the following constraints: 1) it is the feature of English that in initial position, i.e. before the vowel, there can be any consonant except //; 2) the central sonorant /w/ never occurs in the syllable final position; besides, the central sonorants /w, r, j/ are always followed by a vowel, e.g.: winter /^|/, written /^|/, yellow /^|/, i.e. they are used in a SVC syllable type; besides nasal sonorants /m, n/ as well as the lateral sonorant /l/ are capable of forming syllables, e.g.: garden /^| – /, little /^| – /; rhythm /^| – /; 3) the sound // is rare in a word initial position, but it does appear in rather recent borrowings like gigolo, jabot; 4) no consonant combinations are possible with /, , /; 5) such consonant clusters as /pw, bw, tl, dl, / never occur initially.

Phonotactic possibilities of English phonemes predetermine the rules of syllable division:

1) English historically short vowels under stress (checked vowels) occur only in a closed syllable, /; the boundary between the syllables lies after the consonant or within it, as in bigger /b/;

2) English historically long vowels: monophthongs, diphthongs and unstressed short monophthongs (free vowels) can occur both in the open and in the closed syllables. When there is a cluster of consonants between two vowels, the place of the syllabic boundary is conditioned by whether this cluster is permitted at the beginning of words or not;

3) When two vowels are separated by more than two consonants, as, for instance, in the word extra /ek - str/ or /eks - tr/, the boundary may be both before /s/ and /t/ because both /str/ and /tr/ occur at the beginning of words;

4) The so-called thriphthongs in English are disyllabic combinations.
