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.
Non-palatalized: the middle of the tongue is in a neutral position, it does not take part in the 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).
