fidelity

Faithfulness to commitment

Fidelity is faithfulness—to a person, a promise, or a principle.

In relationships, it usually means sexual exclusivity: She never questioned his fidelity.

In broader contexts, it suggests loyal adherence: fidelity to the Constitution, fidelity to one's word.

The word also describes how accurately something reproduces an original—high-fidelity audio captures sound with minimal distortion, and a translation praised for its fidelity stays true to the source text.
