A voiceless retroflex plosive or stop is a type of consonantal sound, used in some spoken languages. This consonant is found as a phoneme mostly (though not exclusively) in two areas: South Asia and Australia.
The symbol that represents this sound in the International Phonetic Alphabet is . Like all the retroflex consonants, the IPA symbol is formed by adding a rightward-pointing hook extending from the bottom of "t" (the letter used for the equivalent alveolar consonant). In many fonts lowercase "t" already has a rightward-pointing hook, but is distinguished from by extending the hook below the baseline.
