köken: From Vulgar Latin *garra, from Gaulish *garra (“leg”) (compare Welsh gar), from Proto-Celtic *garros, which is of uncertain origin; possibly sharing a Pre-Greek / substrate origin with Ancient Greek ἄκαρα (ákara, “leg, shank”).
köken: Borrowed from French ligament, itself a borrowing from Latin ligāmentum, from ligō (“tie, bind”). By surface analysis, liga + -ment. Compare legământ, an inherited doublet.
köken: From Old Norse sina, sin (“sinew”), from Proto-Germanic *senawō, cognate with Swedish sena, English sinew, German Sehne, Dutch zenuw. The word possibly goes back to Proto-Indo-European *snéh₁wr̥, which is also the source of Latin nervus, Ancient Greek νεῦρον (neûron).
