noun
alveolar lateral flap
Technical term in phonetics for a consonant sound produced by a brief tap of the tongue against the alveolar ridge with lateral airflow. In Japanese, this is the sound represented by the 'r' in words like らりるれろ when pronounced quickly.
日本語の「ら行」の子音は、歯茎側面はじき音として調音されることが多い。
The consonant in the Japanese 'ra' row is often articulated as an alveolar lateral flap.
Refers to an alveolar flap (central, not lateral), such as the 't' in American English 'water'. The lateral flap involves airflow around the sides of the tongue.
Compound of 歯茎 (alveolar ridge), 側面 (lateral), and はじき音 (flap sound). The term is a direct descriptive coinage in Japanese linguistics.
