credible

The word 'credible' originates from the Latin adjective 'crēdibilis', meaning "worthy of belief". This Latin term is built directly from the verb 'crēdere' (to believe, trust, entrust) combined with the adjectival suffix '-ibilis', which denotes capability. The root 'crēdere' itself is thought to derive from the Proto-Indo-European compound ḱred dʰeh₁-, meaning "to place one's heart," a concept linking trust to the innermost self. Over time, the literal sense of "entrusting one's heart" evolved into the abstract notion of belief, and 'credible' entered English in the 14th century to describe something or someone that can be trusted and is therefore convincing.

Structure: cred (believe) + ible (able to be) - cred: From Latin 'crēdere' (to believe, trust). In English, it functions as a bound root meaning "belief" or "trust". - ible: A suffix from Latin '-ibilis', meaning "able to be". It forms adjectives indicating capacity or worthiness.
