A thing Ćwarmin has with regards to body parts is separate words for left and right instance of them; this even extends to things that are not "bodyparts" per se, but rather features of bodyparts - such as the corners of the mouth.
togol face, *t'ougo head
sala the right eye, *salak, pupil of the eye, from **slehk, "spot"
ciŋi the left eye, *kjenxi eye
sala in its plural form can either signify 'eyes' or 'right eyes' depending on context; ciŋi is almost never used in the plural.
mogo nose, *muogɔl
rolca nostril, *rɔr hole (exceptionally lacks left and right words)
tərvi right corner of the mouth, *tɛzbü, corner of the mouth
londu left corner of the mouth, *lɔlduk, fold
tuka right cheek, *tuwkas cheekAnother pair of words with a similar pairing are the words for hands:
kolna left cheek, *k'ɔlma chin
envə chin, *önüɛ jaw
ruxan right ear, *ruskan
cəvəl left ear, *kɛvl
ćimbi any tooth of the upper row of teeth, from *ksümbü, fang
lom any tooth of the lower row of teeth, from *lmɔ, tooth
ruanas hair, *ruhɔnaz
gotoka bald spot, *gotom leather
samǧa beard, *sawgas beard
vilke right hand *xvülk'ö, hand
talto left hand *t'artwa, branch
The left-right symmetry of the human body is a very central concept in early Ćwarmin liturgies, rituals, myths and gestures.
