Mike, Alan, Here is I think the 'kopar' declension in Icelandic, which shouldn't be much too different from its Norse relative... (kopar-inn)... nominative : kopar accusative : kopar dative : kopari genitive : kopars And I am not sure whether plural forms are very relevant here for 'copper' ! Bara pinulitidh, sori !... Bless, Yann.
