The Free On-line Dictionary of Computing (19 January 2023):

inheritance

    In object-oriented
   programming, the ability to derive new classes from
   existing classes.  A derived class (or "subclass") inherits
   the instance variables and methods of the "base class"
   (or "superclass"), and may add new instance variables and
   methods.  New methods may be defined with the same names as
   those in the base class, in which case they override the
   original one.

   For example, bytes might belong to the class of integers for
   which an add method might be defined.  The byte class would
   inherit the add method from the integer class.

   inheritance.
