Usage

Errata is originally the plural of the singular Latin noun erratum. Like many such borrowed nouns (agenda; candelabra), it came by the mid-17th century to be used as a singular noun, meaning "a list of errors or corrections to be made (in a book).'' Despite objections by some to this singular use, it is common in standard English:
The errata begins on page 237.
When errata clearly means "errors,'' it takes plural verbs and pronouns:
Although errata were frequent in the first printing, most of them were corrected in subsequent printings.
As a singular noun, errata has developed an English plural form erratas, which is rarely used.
