From The Free On-line Dictionary of Computing (8 July 2008) [foldoc]:
reuse
reusability
Using code developed for one application program in another
application. Traditionally achieved using program libraries.
Object-oriented programming offers reusability of code via
its techniques of inheritance and genericity. Class
libraries with intelligent browsers and {application
generators} are under development to help in this process.
Polymorphic functional languages also support reusability
while retaining the benefits of strong typing.
