köken: Semantically similar to Proto-Indo-European *bʰedʰh₂- (“to pierce, to dig”), however, the expected outcome of this root in Greek would be **πόθρος (**póthros) (based on Grassmann's law). Pre-Greek origin or influence from Ancient Greek βαθύς (bathús, “vertically distant (high/deep)”) are possible alternatives.
Allegedly named after a French person Chambeau, but no such person has been identified. Others suggest it may come from French chambre. Compare pot de chambre. Also found as Russian шамбо (šambo), Armenian շամփո /շամփօ (šampʻo).
