Articles behave as adjectives in the sense that they agree in gender, number and case with the nouns they modify. These attributes have almost all the values presented in the relevant sections for Nouns, with the exception of masc-fem and common for Gender, invariant for Number and voc and indcl for Case. Certain forms are monographs, necessitating the use of a disambiguation procedure during corpus tagging:
``tou vivliou'' -- neut. gen.
``tou anthrwpou'' -- masc. gen.
but
``to exwfullo'' -- neut. nom./acc.
