Coronal

On the IPA chart, sounds are described according to where in the mouth they are made; but it is equally important to think about which part of the tongue is used to make them. Dental, alveolar, postalveolar and retroflex sounds are all made with the front part of the tongue, the tip (the very frontmost part of the tongue) or the blade (the part just behind the tip). There is a lot of variability among English speakers as to which part of the tongue they use to articulate dental, alveolar and postalveolar sounds, so usually this factor is ignored, since it seems to play no linguistic role for English. In the phonology literature, sounds made with the front part of the tongue are often called coronal, a term which does not appear on the IPA chart. (The Latin word ‘corona’ means ‘crown’; this is the term used to refer to the front part of the tongue.
