An apical consonant is a
phone (speech sound) 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
Hadhrami Arabic (also spelt Hadrami), realizes [t] as laminal but [d] as apical.
