|Etymology is the study of historical linguistic change, which occurs due to the development of a particular word or element of a word, often delineating its spread from one language to another and its evolving changes in form and meaning. They're explanations of what our words meant and how they sounded 600 or 2,000 years ago.
Peer review refers to the work done during the screening of submitted manuscripts and funding applications. This process encourages authors to meet the accepted standards of their discipline and reduces the dissemination of irrelevant findings, unwarranted claims, unacceptable interpretations, and personal views. Publications that have not undergone peer review are likely to be regarded with suspicion by academic scholars and professionals.
