English orcin
From French orcine, from New Latin orcina, from Dutch orseille, from French orseille, from Old French orchel, orseil, from Old Catalan orxella (influenced by dialectal Arabic [script needed] ('urjālla)), from Italian oricello, from Latin ōricilla, diminutive of ōricula (variant of auricula), both diminutives of auris (“ear”)) + illa (a double diminutive suffix) or from auris (“ear”) + cula + illa. The name of the dye was influenced by the visual resemblance of the lichen used in production to a small ear.
