Podcast 1 — Introduction & meaning

Narrator: Today's word is "Fidelity" — noun, pronounced /fɪˈdɛlɪti/, with the stress on "del".

Narrator: Fidelity is faithfulness to a person, cause or belief, or accuracy in reproduction.

Narrator: In plain English, fidelity is loyalty — like fidelity in marriage, or the fidelity of a sound recording.

Narrator: It comes from the Latin fidelitas, meaning faithfulness, from fidelis, faithful, from fides, faith.

Narrator: "Marital fidelity" describes faithfulness within a marriage.

Narrator: It differs from loyalty because fidelity can also mean accuracy, whereas loyalty is about allegiance.

Narrator: Relationships, audio, genetics, science and everyday speech all rely on the word fidelity.

Narrator: So remember: fidelity means faithfulness, from the Latin for faith.
