The bare letters , 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: , "etc.", though that could also mean extra-retracted. The letters are frequently called 'alveolar', and the language examples below are all alveolar sounds.
