The paper presents the role of multiple semantic inheritance that may be used in the Object
Oriented Approach (OOA). The aim of the OOA, proposed by Wiesław Banyś at the University of
Silesia, is to organise the language description in the form of a lexical data base easily implemented
and used in automatic translation. Semantic inheritance is one of the most important features of the
AOO and takes place when an object or an object class inherits operations and/or attributes from its
super-object class while multiple inheritance is when an object or an object class can inherit semantic
characteristics from more than one super-class.
Some Object-Oriented Programming languages let the implantation of multiple inheritance,
which, if the procedure is not abused and treated as emergency solution, makes the AOO description
responding to every modification of human language and reflects every new language item in that
lexical date base
