Morality, n.; pl. Moralities.
Etymology: [L. moralitas: cf. F. moralité.]
1. The relation of conformity or nonconformity to the moral standard or rule; quality of an intention, a character, an action, a principle, or a sentiment, when tried by the standard of right. The morality of an action is founded in the freedom of that principle, by virtue of which it is in the agent's power, having all things ready and requisite to the performance of an action, either to perform or not perform it. South.
2. The quality of an action which renders it good; the conformity of an act to the accepted standard of right. Of moralitee he was the flower. Chaucer. I am bold to think that morality is capable of demonstration. Locke.
3. The doctrines or rules of moral duties, or the duties of men in their social character; ethics. The end of morality is to procure the affections to obey reason, and not to invade it. Bacon. The system of morality to be gathered out of ... ancient sages falls very short of that delivered in the gospel. Swift.
4. The practice of the moral duties; rectitude of life; conformity to the standard of right; virtue; as, we often admire the politeness of men whose morality we question.

Shades of meaning
Fernald has no entry of its own for morality; he lists it under religion, virtue.
Where he writes about it:
Morality is the system and practise of duty as required by the moral law, consisting chiefly in outward acts, and thus may be observed without spiritual rectitude of heart; morality is of necessity included in all true religion, which involves both outward act and spiritual service. — from religion
Morality is conformity to the moral law in action, whether in matters concerning ourselves or others, whether with or without right principle. — from virtue
