The inventory of words relating to property and heritage, possession, right of ownership and inheritance in the Albanian customary legal norms included in the so-called Kanun i Lekë Dukagjinit is rich and stable. Most of the words are ancient (autochthonous or borrowed from Latin, but also from Greek and Italian) and correspond to definite realities. There are even terms which do not go beyond the limits of the Gheg dialect. With a few exceptions, these are the words in the common vocabulary that gain legal meanings. Fixed and sometimes rhymed synonymic formulas and series facilitate oral transmission from generation to generation.
