erkan

• erchan, erchno, erchen, ercn

Apparently from Proto-Germanic *erknaz, thus cognate with 𐌰𐌹𐍂𐌺𐌽𐍃 (airkns, “holy, pure (of faith)”) and Old English eorcnanstan (“precious stone, gem”) (see eorcnan, erce). An archaic Germanic word from the sacral sphere, its original meaning is difficult to reconstruct as it belonged to the pagan religious vocabulary obscured after Christianization.

Pokorny (1959) tentatively groups the word with Proto-Indo-European *h₂erǵ- (“glittering, white”) (compare Ancient Greek ἀργός (argós), Latin argentum).
