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" (, "etc.") may be used for a dental consonant, or the under-bar (, "etc.") may be used for the postalveolars. differs from dental in that the former is a sibilant and the latter is not. differs from postalveolar in being unpalatalized.
