Reviewer comes from review + -er. Review derives from Middle French reveue ('a viewing again'), from re- ('again') + veue ('a viewing'), from veoir ('to see'), from Latin videre ('to see'). The historical chain includes Middle French reveue, Latin videre, and Proto-Indo-European *weyd-. Older glosses in the chain include "a viewing again", "again", "a viewing", and "to see", which help explain the semantic range of the modern word. Morphologically, reviewer is best read as compound, suffixal formation, and borrowing, yielding an English noun shaped by both form history and later usage. In current English it functions as a noun, with the sense "a person who writes critical assessments of books, films, or work". related forms include review, preview, view, and interview. The result is an English noun whose etymology preserves the older forms while supporting the word's specialized modern meaning.
