Pronunciation

  • US: /ʌnˈdɒkjəmentɪd/, /ʌnˈdɑːkjəment̬ɪd/[1]

Etymology

It is formed from English un- + documented,[2][3][4][5] the second part being the past participle of the verb document.[6][3][4] The OED compares the earlier well-documented.[2]

Earliest recorded meaning

Not supported or recorded by documents: Merriam-Webster dates this sense to 1867,[4] while the OED's first record is from the Boston Herald of 12 May 1883,[2] the date Etymonline also gives;[6] Dictionary.com has 1880–85.[5]

Semantic evolution

In the United States the word came to mean not having the legal documents or licence that are required,[2][6][3] which Collins labels as American.[7] Merriam-Webster records a use of a boat, not registered or licensed.[4] Applied to people, it describes immigrants who live or work in a country without official papers;[7][2] undocumented worker, an illegal immigrant in employment, is recorded by 1977.[6]
