erratum, errata

Erratum, derived from a Latin verb meaning "to wander," means "an error," one usually resulting from a misprint in a book or any mistake in something written by hand. Errata is the plural form of this noun and requires a plural verb: "The errata in this volume are numerous." Errata may also mean a list of errors or corrections, but even in this meaning is preferably followed by a verb in the plural. The word erratas is sometimes found in print, but the form is not generally approved."The one important erratum in the volume was noted on an inserted page." "The major errata in this work have been listed in an appendix."
