Lateral flap

A lateral flap is a family of consonantal sounds, used in some spoken languages.

There are four attested or claimed lateral flaps in the world's languages:
 * The alveolar lateral flap is quite common.
 * A retroflex lateral flap  is found throughout South Asia, from Pashtun to Oriya, in the Iwaidjan languages of Australia, and sporadically elsewhere.
 * A palatal lateral flap has been described from Iwaidja, but the authors note that it may be a palatalized alveolar flap.
 * A velar lateral flap occurs allophonically in Melpa and a few other languages of New Guinea.
