Etymology Origin:
The word faith traces back to the Latin fides, meaning "trust" or "loyalty," which evolved into Old French feid before entering Middle English as faith. The suffix -th (like in truth, growth) solidifies it as an abstract noun. The core idea of "trust" has remained central, though its usage expanded to include religious devotion.
