n. The tie or obligation of a subject or citizen to his sovereign or government; the duty of fidelity to a king, government, or state.n. Hence Observance of obligation in general; fidelity to any person or thing; devotion.n. Synonyms Allegiance, Loyalty, Fealty. Allegiance is the most formal and official of these words; it is a matter of principle, and applies especially to conduct; the oath of allegiance covers conduct only.n. Loyalty is a matter of both principle and sentiment, conduct and feeling; it implies enthusiasm and devotion, and hence is most frequently chosen for figurative uses: as, loyalty to a lover, husband, family, clan, friends, old traditions, religion. Neither allegiance nor loyalty is confined to its original meaning of the obligation due from a subject to a prince.n. Fealty has escaped less completely from this earliest sense, but has a permissible use in the sense of fidelity under obligation of various kinds.
