consonants are articulated
with the tongue against or close to the superior alveolar ridge
, which is called that because it contains the alveoli
(the sockets) of the upper teeth. Alveolar consonants may be articulated with the tip of the tongue (the apical consonants
), as in English, or with the flat of the tongue just above the tip (the "blade" of the tongue; called laminal consonants
), as in French and Spanish.
The International Phonetic Alphabet
(IPA) does not have separate symbols for the alveolar consonants. Rather, the same symbol is used for all coronal
places of articulation that are not palatalized
like English palato-alveolar sh
, or retroflex
. To disambiguate, the bridge
([s̪, t̪, n̪, l̪], etc.
) may be used for a dental consonant, or the under-bar
([s̠, t̠, n̠, l̠], etc.
) may be used for the postalveolars
. [s̪] differs from dental [θ] in that the former is a sibilant
and the latter is not. [s̠] differs from postalveolar [ʃ] in being unpalatalized.
The bare letters [s, t, n, l], etc. cannot be assumed to specifically represent alveolars. The language may not make such distinctions, such that two or more coronal places of articulation
are found allophonically
, or the transcription may simply be too broad to distinguish dental from alveolar. If it is necessary to specify a consonant as alveolar, a diacritic from the Extended IPA
may be used: [s͇, t͇, n͇, l͇], etc.
, though that could also mean extra-retracted.
The letters ⟨s, t, n, l⟩ are frequently called 'alveolar', and the language examples below are all alveolar sounds.
(The Extended IPA diacritic was devised for speech pathology
and is frequently used to mean "alveolarized", as in the labioalveolar sounds [p͇, b͇, m͇, f͇, v͇], where the lower lip contacts the alveolar ridge.)
Alveolar consonants are transcribed in the IPA as follows:
Lack of alveolars
The alveolar or dental consonants
[t] and [n] are, along with [k], the most common consonants in human languages.
Nonetheless, there are a few languages that lack them. A few languages on Bougainville Island
and around Puget Sound
, such as Makah
, lack nasals and therefore [n], but have [t]. Colloquial Samoan
, however, lacks both [t] and [n], but it has a lateral alveolar approximant
/l/. (Samoan words written with t
are pronounced with [k] and [ŋ] in colloquial speech.) In Standard Hawaiian
, [t] is an allophone of /k/, but /l/ and /n/ exist.
In labioalveolars, the lower lip contacts the alveolar ridge. Such sounds are typically the result of a severe overbite. In the Extensions to the IPA
for disordered speech, they are transcribed with the alveolar diacritic on labial letters: ⟨m͇ p͇ b͇ f͇ v͇⟩.
