Features of the voiceless alveolar lateral affricate:
Its manner of articulation is affricate, which means it is produced by first stopping the airflow entirely, then allowing air flow through a constricted channel at the place of articulation, causing turbulence.
Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
It is an oral consonant, which means air is allowed to escape through the mouth only.
It is a lateral consonant, which means it is produced by directing the airstream over the sides of the tongue, rather than down the middle.
