Both deriving ultimately from the Latin habilis, the English verbs habilitate and enable both have to do with the gaining or demonstration of ability. However, the verb habilitate differs from the verb enable by the narrower scope of its action. Under enable are subsumed the general senses of: (1) the conferring of sufficient ability or power for something, (2) to qualify or approve for some role or position, (3) to permit or authorize, (4) to affirm, (5) the yielding of possibility or opportunity for something, (6) to excuse some action or behavior, (7) to activate as part of a system. To habilitate only includes (1), (2), and (3) of the above, including, variously, the specific senses of the conferring of power or ability, qualification and authorization. The verb to habilitate, in this way, can be viewed as a "partial synonym" of the verb to enable.
