Where it comes from

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).
