ABSTRACT
English has other consonants which, phonetically, can be classified as double articulations. The English [1]-sound, for example, has open post-alveolar approximation. Simultaneously, however, it has open lip rounding (not at all unlike [w]). Technically, therefore, we are dealing with_ a iabiai-postalveolar approximant. Likewise palato-alveolar [f] and [3] (called, misleadingly, postalveolar by the IPA) have simultaneous narrow approximation at the palate and the alveolar ridge.
