peer-reviewed

The term 'peer-reviewed' is a modern compound adjective, primarily emerging in the 20th century with the formalization of academic publishing standards. Its first element, 'peer', traces back to the Latin 'par' (equal), reflecting the core principle that evaluation is conducted by equals in expertise and standing. The second element, 'review', originates from the Latin 'revidere' (to see again), implying a careful, re-examining scrutiny. Combined, the term literally means "having been examined again by equals," a process designed to ensure the validity, quality, and originality of scholarly work before it enters the public domain.
