From Middle English obelus, obelo, from Old English obelus, from Late Latin obelus (“critical mark”), from Koine Greek ὀβελός (obelós, “critical mark”), Ancient Greek ὀβελός (obelós, “rod, spit; obelisk; critical mark”). The further etymology is uncertain; a derivation from βέλος (bélos, “arrow, dart, missile”) (from Proto-Indo-European *gʷelH- (“to pierce; to reach; to throw; to hit by throwing”)) has been suggested, but the initial vowel remains unexplained. Compare obelisk. The plural form obeli is derived from Late Latin obeli, from Ancient Greek ὀβελοί (obeloí).
