  • US: /ɪnˈtɛɹəɡeɪt/[1]

Etymology

It is borrowed from Latin interrogātus, the past participle of interrogō (“to ask, question, examine”),[2][3][4][5] which is formed from inter- (“between, at intervals”) and rogō (“to ask”).[2][3][6] Barnhart and Etymonline think it may instead, or also, be a back-formation from interrogation,[7][3] recorded about 1390 in Chaucer.[7][8] Skeat took the prefix here as "thoroughly".[9] Etymonline explains the Latin verb for asking as apparently a figurative use of a verb meaning "to stretch out the hand", from Proto-Indo-European *reg- (“to move in a straight line”).[3] The American Heritage Dictionary gives an early form enterrogate,[10] and the Shorter Oxford also has the spelling enterrogate.[11] The verb in Old French was interroger, the source of interroge, a now obsolete verb of the late 15th century.[3]

Earliest recorded meaning

To question closely: 1483, in Caxton's translation of Cato.[2][7]

Semantic evolution

It widened in the 17th century to asking questions in general, as in Bacon's Henry VII (1622),[2][12] a use the Shorter Oxford marks as chiefly legal.[11] A short-lived use, "to ask about (something)", ran from 1600 to 1698.[2] Johnson (1755) entered the transitive verb, "to examine; to question", and the intransitive one, "to ask; to put questions".[12] The 17th century also had an adjective (1625) and a noun for a question (1633–49), both now obsolete.[2] In the 20th century the word moved to machines: to cause a transponder to send a signal (1945), and to get information from a computer memory (1964).[2][11]
