[Edit]

An apical consonant is a phone produced by obstructing the air passage with the apex of the tongue (i.e. the tip of the tongue). This contrasts with laminal consonants, which are produced by creating an obstruction with the blade of the tongue (which is just behind the apex).

This is not a very common distinction, and typically applied only to fricatives and affricates. Thus many varieties of English have either apical or laminal pairs of [t]/[d]. However, some varieties of Arabic, including Hadrami Arabic, realizes [t] as laminal but [d] as apical.

The Basque language uses this distinction for alveolar fricatives, as does Serbo-Croatian. Mandarin Chinese uses it for postalveolar fricatives (the "alveolo-palatal" and "retroflex" series). St'at'imcets uses this as a secondary feature in contrasting velarized and non-velarized affricates.
