Etymology Origin:
The word "prove" traces back to Latin probare ("to test, approve"), which itself derives from probus ("good, honest"). The term entered English via Old French prover in the 12th century, initially meaning "to test or demonstrate truth." Over time, it narrowed to its modern sense of establishing validity through evidence, while the related word "approve" retained the original connotation of endorsement. The silent -e reflects Middle English spelling conventions.
