Pronunciation

  • /pɹɪˈdɪk.tɪv/[1]

Etymology

It is borrowed from Late Latin praedictīvus (“foretelling, prognosticating”), recorded from the 5th century,[2][3][4][5][6] formed from praedictus, the past participle of praedīcō (“to foretell, give warning of”), with the suffix -īvus.[2][4] The Latin verb is from prae- (“before”) and dīcō (“to say”),[2][3] which Etymonline traces to Proto-Indo-European *deik- (“to show”).[3]

Earliest recorded meaning

Having the quality of predicting the future; prophetic, or foretelling a later event: 1637, in Robert Monro's account of his expedition with a Scots regiment.[2] Etymonline and Dictionary.com date the word to the 1650s.[3][6]

Semantic evolution

From the start the word described both a prophecy and a sign that points to a later event, often followed by of.[2][5] Before 1831 Jeremy Bentham used it in grammar for the future tense when it states only what will happen, with no intention or obligation on the part of the subject.[2] Late 20th-century technology added two senses: from 1982, systems that guess the word being typed from the text already entered, the source of predictive text on mobile phones,[2][7] and since 1988, in photography, an autofocus that keeps a moving object in focus.[2]
