Based on Maciołek & Tambor (2012)
Voiced: the vocal folds are in contact, the air coming from the lungs causes them to vibrate.
Alveolar: the front part of the tongue lies against the alveolar ridge and the teeth.
Non-palatalized: the middle of the tongue is in a neutral position, it does not take part in the articulation.
Lateral: there is a closure between the tongue tip and the alveolar ridge. Between the sides of the tongue and the premolars there is a passage which is larger than with fricatives and through which the air from the lungs can pass freely.
