Nasal vowel
Encyclopedia
A nasal vowel is a vowel
that is produced with a lowering of the velum
so that air escapes both through nose
as well as the mouth
. By contrast, oral vowels are ordinary vowels without this nasalisation. The term "nasal" is slightly misleading as the air does not come exclusively out of the nose in nasal vowels.
In most languages, vowels that are adjacent to nasal consonant
s are produced partially or fully with a lowered velum in a natural process of assimilation
and are therefore technically nasal, though few speakers would notice. This is the case in English
: vowels preceding nasal consonants are nasalized, but there is no phonemic
distinction between nasal and oral vowels (and all vowels are considered phonemically oral). However, the word "huh" is generally pronounced with a nasal vowel.
In French
and Portuguese
, by contrast, nasal vowels are phonemes distinct from oral vowels, since words that differ mainly in the nasal or oral quality of a vowel exist. For example, the French words beau /bo/ "beautiful" and bon /bõ/ "good" differ only in that the former is oral and the latter is nasal. (To be more precise, the vowel in bon is slightly more open
, leading many dictionaries to transcribe it as /ɔ̃/.)
and the nose
, producing an invariant and sustainable vowel quality. That is, this type of nasalization is synchronic and suprasegmental to the voicing. In contrast, nasal vowels in French or Portuguese
are transitional, where the velum
ends up constricting the mouth
airway.
In languages that have transitional nasal vowels, it is common that there are fewer nasal vowels than oral ones. This appears to be due to a loss of distinctivity caused by the nasal articulation.
may cause a vowel's articulation to shift. However, while nasalization due to the assimilation
of a nasal consonant
will tend to cause a raising of the vowel's height, phonemically distinctive nasalization tends to lower the vowel. In most languages, vowels of all heights are nasalized indiscriminately, but preference occurs in select few languages, such as to high vowels in Chamorro
and low vowels in Thai
.
may indicate nasal vowels by a trailing silent
n or m, as is the case in French, Portuguese, Bamana
, or Yoruba
; others use diacritic
al symbols (Portuguese also employs a tilde
~ on ã, õ, before vowels; Polish
, Navajo
, and Elfdalian use a hook underneath the letter, called an ogonek
, as in ą, ę). Other languages may use a superscript n: aⁿ, eⁿ. In the International Phonetic Alphabet
, nasal vowels are denoted by a tilde over the symbol for the vowel, as in Portuguese.
Abugida
scripts, which are used for most Indian languages, use the chandrabindu
(◌̐) diacritic and its variations to denote nasal vowels and nasal junctions between consonants.
The Nasta'liq script used by Urdu
denotes nasalization by employing the Arabic letter ˂ن˃ nūn but removing the dot (˂ں˃), called nūn ghunna. Nasalized vowels occur in classical Arabic, but not in contemporary speech or standard Arabic. There is no orthographic way to denote the nasalization, but it is systematically taught as part of the essential rules of tajweed employed while reading the Qur'an
. Nasalization usually occurs in recitation when a final ˂ن˃ nūn is followed by a ˂ي˃ yāʼ
Vowel
In phonetics, a vowel is a sound in spoken language, such as English ah! or oh! , pronounced with an open vocal tract so that there is no build-up of air pressure at any point above the glottis.
