The voiceless alveolar stop is a type of consonantal sound used in many spoken languages. The symbol in the International Phonetic Alphabet that represents voiceless dental, alveolar, and postalveolar stops is ⟨t⟩, and the equivalent X-SAMPA symbol is t. The dental stop can be distinguished with the underbridge diacritic, ⟨t̪⟩, the postalveolar with a retraction line, ⟨t̠⟩, and the Extensions to the IPA have a double underline diacritic which can be used to explicitly specify an alveolar pronunciation, ⟨t͇⟩.
The [t] sound is a very common sound cross-linguistically; the most common consonant phonemes of the world's languages are [t], [k] and [p]. Most languages have at least a plain [t], and some distinguish more than one variety. Some languages without a [t] are Hawaiian (except for Ni‘ihau; Hawaiian uses a voiceless velar stop [k] for loanwords with [t]), colloquial Samoan (which also lacks an [n]), Abau, and Nǁng of South Africa.
