6.2 Number of Syllables
(1) Even in uncommonly used vocabulary such as
comsumptiveness [kən.ˈsʌmp.tɪv.nɪs], docility [dɑ.sí.lə.ti],
divinatory [di.ví.nə.tə.ri], cosmographical [kɒz.mɒ.ɡrǽ.fɪ.kəl]
([kaz.mo.ɡrǽ.fɪ.kəl] AE), most English speakers know that
‘consumptiveness’ and ‘docility’ have 4 syllables, and ‘divinatory’
and ‘cosmographical’ have 5 syllables.
Depending on native speakers’ intuition, it seems that English
speakers
recognize how many syllables the words have without any
difficulty when they speak.
Syllables can be produced based on vowels. So generally it is
considered that the number of syllables is the same with the
number of vowels involving syllabic consonants in a word. And
the production of syllables contributes to ease of communication
with a large amount of sonority(amount of resonance). Therefore,
the language that we use necessarily consists of resonance of
vowels whose waves could carry sounds easily. All the languages
that we use must have syllables. If there is no syllable, languages
will not exist. The syllable is significantly important in languages.
By the way, in the syllable, the vowels play an important role as a
syllable peak.
A single vowel without any consonants can produce a syllable.
For example, the exclamations such as ‘Ah’, ‘Oh’, ‘Wow’ produce a
syllable because each of them has a vowel as [a:], [oʊ], [waʊ].
Thus a syllable can be created by a single vowel without
consonants.
(3) The syllabic nasal is one of the syllabic consonants. The
syllabic consonants include [m, n, ŋ, l, r]. These sounds play a
similar role to a vowel when they are placed after other
obstruents in the syllable-final position.
Only in this environment, syllabic consonants can be created by
having the similar function to vowels with more sonority as a
syllable peak.
