The word 'faith' refers to a strong belief or trust in something or someone, often without needing proof. It can involve religious belief, trust in other people, or confidence in a particular concept or system. Faith is considered a deeply held conviction, where one embraces ideas or commitments despite uncertainties or lacking evidence.
The word 'faith' originates from the Latin word 'fides,' which means trust or belief. It entered Middle English through Old French 'feid,' which carried a similar meaning. Over time, it has retained its association with a deep-seated belief or trust.
