Entry: tsiʔsu
Grammar: n.
Meaning: the flank and the fleshy portion of the lower back, the general area surrounding the kidneys
Derivation: [tsiʔi 'god' + su 'meat'] [?]
Comments: this part of the body is so called because pains localized in this area are believed to be inflicted by angered deities and because the area is viewed as being particularly vulnerable, e.g. a stab with a dagger in this area is considered to be lethal.
