Etymology

From Ancient Greek ἀ- (a-, the alpha privativum, a prefix forming words having a sense opposite to the word or stem to which it is attached; a-) + δέρμα (dérma, “skin”) + γλυφή (gluphḗ, “carving”) + -ία (-ía, suffix forming feminine abstract nouns); analysable as a- + dermato- + glyph + -a.
