credential

Etymology

It is inherited from Middle English credencial,^[2][3] borrowed from Medieval Latin crēdentiālis (“giving credence, recommending”),^[4][5][6][7] which was used from the 13th century in the phrase littere credentiales, letters of credence.^[4] The Medieval Latin adjective is formed from crēdentia (“belief, trust”), the source of credence, and Latin -ālis,^[4][6][8] and the noun goes back to Latin crēdō (“to believe, trust”).^[9] Etymonline takes the singular noun as probably a back-formation from the plural credentials.^[9]

Earliest recorded meaning

Serving as a recommendation or introduction, in credential letters: 1433, in a charter now in the Edinburgh Register House.^[4] The Middle English Dictionary quotes letres credenciales, confirming letters, from a text of 1470.^[2] Etymonline dates the adjective to the late 15th century.^[9]

Semantic evolution

The Oxford Dictionary of English notes that the word was first an adjective, chiefly in credential letters, and that the noun credentials followed in the mid 17th century.^[7] The plural, for the letters that commend an ambassador or other envoy to a foreign government, appears in 1648 and the singular in 1656;^[4] Merriam-Webster Unabridged dates the noun to 1655,^[6] while Etymonline puts the singular at 1756 and calls it rare.^[9] Already in 1651 the word was used figuratively for whatever recommends a person, such as a qualification or achievement,^[4] and Johnson (1755) defined it as the warrant on which belief or authority is claimed.^[10] The adjective is now rare.^[11] The verb, to supply with credentials, is first quoted from before 1860;^[4] Etymonline finds it implied in credentialed by 1828,^[9] and Merriam-Webster Unabridged dates it to 1888.^[6]
