Lecc diice (duice, doice) (occurring in legal texts, such as Gúbretha Caratniad §15 and the legal commentary at CIH i 145.10-37, of which an English translation is given here) refers to ‘a physical defect which made a woman incapable of intercourse’; diice may, as suggested by R. Thurneysen (in ZCP 16 (1927), pp. 217-218 [Best² 2157]), represent do-ícce ‘incurability’ or, posssibly, an abstract based on diic, diing ‘difficult’.
