AVT (Attribute Value Tree) can be considered a generalization of AVM (Attribute Value Matrix) used in many Feature Structured Unification grammars (FSUG). In this paper we give some properties of the AVT like: paths in an AVT, exclusive combinations in an AVT, logical interpretation of an AVT, well formed AVT, the equivalence of the AVTs, the ordered AVTs, the AVTs intersection, the AVTs difference, the AVT normalization, the AVTs unfiability and the AVTs unification. Using these properties, the AVTs can be used more easily in the morphological description of a language, the morphological analysis of a text, the text annotation, the grammar analysis, the generation process and even in an automatic translation
