equipo m. (Noun) "equipment;" (sports) "team"
19th cent. borrowing from French équipe 'id.' From Old French eschiper "to embark," "to load a ship;" itself a borrowing from a Norse word skipa "ship." The word skipa was an ancient borrowing from Latin scyphus "drinking cup," which in turn was borrowed from Greek σκύφος (skyphos) "two-handled wine cup." No further etymology is possible. The word σκύφος has been suspected by Beekes (2014) to be of Pre-Greek origin. Hesychius refers to a rare word κύβος (kybos), which he defined as a drinking vessel, that Furnée (1972) suspects may be a Pre-Greek variant of σκύφος.

Ancient Greek ἄζω (ádzo) "to dry up," from *h2ed-
A asatär "to dry up," B osotär 'id."
Gothic azgo "ashes," English ash, and Armenian azazim "to become dry," ačiwn "ash" look suspiciously close, yet attempts to link them have come up tenuous at best. Perhaps the strongest case has been made by Kroonen (2014), positing a collapse of a very old compound *h2ed-dhgwh-eh2-.
