Etymology

It is from Latin authenticus (“authentic, genuine”), a verb formed in Medieval Latin.[2][3] English took its past participle as the source of authenticate.[2]

Earliest recorded meaning

The earliest dated example in the MLW is an Italian charter of 1185, in which a notary is asked to certify the statements of witnesses and set them down in a public document.[4]

Semantic evolution

In charters of the 12th and 13th centuries it meant to make a document valid by witnesses' signatures and seals, and to certify that a copy matched its original.[4] From this came the senses to have an official copy made, to confirm by a public instrument, to approve or ratify, and to put into force; the MLW also records it in the sense to dedicate.[4] Regional dictionaries of medieval Latin record the same legal sense of confirming by authority in Hungary and Poland.[5][3]

In British sources it is used of stamping something as genuine or authoritative, as when a teaching is confirmed by a general council.[6] Stelten glosses it in Church Latin as to authenticate or verify.[7] Spellings without ⟨h⟩ (autentico, auctentico) are common.[4][1]
