History

Etymology

Borrowed from Late Latin praefīxum, from Latin praefīxus, past participle of praefīgō (“to (fix, fasten, set up) in front”, “to fix on the (end, extremity)”) (from prae- (“before”) + fīgō (“to fix”, “to fasten”, “to affix”)), equivalent to pre- + -fix. Doublet of the archaic synonym prefixum.

From Middle English prefixen, from Middle French prefixer, from Latin praefīxus, past participle of praefīgō (“to (fix, fasten, set up) in front”, “to fix on the (end, extremity)”) (from prae- (“before”) + fīgō (“to fix”, “to fasten”, “to affix”)), equivalent to pre- + -fix.
