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 ɺ 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 ʎ̮ has been described from Iwaidja, but may be a palatalized alveolar flap.
• A velar lateral flap ʟ̆ occurs allophonically in Melpa and a few other languages of New Guinea.

Features

Features of lateral flap:

• Its manner of articulation is flap, which means it is produced with a single contraction of the muscles so that one articulator (usually the tongue) is thrown against another.

• It is a lateral consonant, which means it is produced by directing the airstream over the sides of the tongue, rather than down the middle.
