It is a lateral consonant. It means that we produce this sound by directing the airstream over the sides of the tongue, but not down the middle.
Its behavior is stop, or plosive. It means that we produce this sound by obstructing airflow in the vocal tract. (The term plosive contrasts with nasal stops, where the blocked airflow is redirected through the nose.)
