The word appears in variations (λαυκανίη, λαυχάνη) meaning throat, neck, tongue. There is no indication that this homeric word was exclusive to Macedonian vocabulary, other than the fact that Amerias mentions it. The lack of Indo-European correspondences and the existence of a variant with χ, points to a pre-Greek origin.
