positional variant (does not occur in isolation)
Based on Maciołek & Tambor (2012)
Voiceless: the vocal folds are separated, not vibrating, the air flows freely between them.
Alveolar: the front part of the tongue lies against the alveolar ridge and the teeth.
Palatalized: the middle of the tongue gets closer to the hard palate as a secondary articulation.
Affricate: the air from the lungs first meets an obstacle in the form of a closure in the oral cavity (cf. plosives), which subsequently changes into a narrow passage (cf. fricatives).
