Etymology

It is borrowed from Late Latin malignāns (“acting maliciously”), the present participle of malignō (“to act maliciously, contrive maliciously”),[2][3][4][5][6][7] a verb of the Vulgate.[2] Etymonline adds that it came also from French malignant,[8] and the OED compares Anglo-Norman malignant (“an evil-doer”), recorded from about 1120, and Middle French malignant (about 1500).[2][9] The verb comes from Latin malignus (“wicked, ill-disposed”),[2][8][10] formed from male (“badly”) (from malus (“bad”)) and -gnus (“born”), from gignō (“to beget”), from Proto-Indo-European *gene- (“to give birth, beget”).[8] Klein compares benignant.[11]

Earliest recorded meaning

Disposed to rebel against God or against established authority; disaffected: 1542, in H. Brinkelow's Lamentacion.[2][3] The Oxford Dictionary of English likewise dates the word to the mid 16th century, with this early sense,[12] and Dictionary.com to 1535–45.[6] Etymonline starts with the medical sense, "virulent, tending to produce death", in the 1560s.[8]

Semantic evolution

The word was first used with allusion, often in Protestant polemic, to the Vulgate's Psalm 25:5, “Odivi ecclesiam malignantium”, and the church malignant, the followers of Antichrist, was applied by Protestant writers to the Church of Rome.[2][8] In the English Civil War, from 1641, supporters of Parliament called the Royalists malignants,[2][12][10] and in 1642 Charles I turned the name back on the Parliamentary party.[13] Of diseases, the word meant potentially fatal, extremely severe or highly contagious from 1568, in a description of the plague;[2] it is now used chiefly of tumours that invade nearby tissue and spread.[2][3][10] Of people, "full of intense ill will" is recorded from 1592,[2] and Etymonline dates "disposed to cause suffering" to the 1590s.[8] From 1608 it also meant exerting an evil influence, and in astrology it was used of the stars and planets, as in Shakespeare's Henry VI, Part 1.[2][3] Johnson (1755) defined it as malign, envious and malicious, quoting Shakespeare's "O malignant and ill-boading stars!".[14] Middle English had used the simpler malign as the adjective.[8]
