Forms

lunatic m or n (feminine singular lunatică, masculine plural lunatici, feminine/neuter plural lunatice)[1]

Etymology

It is borrowed from Latin lūnāticus (“moonstruck, epileptic”), and in its modern senses also borrowed from French lunatique.[2][3][4][5] The neologism dictionaries add Italian lunatico.[6] Tiktin thinks the word probably came through Church Slavonic, which had also taken the Latin word.[7][8] Wiktionary instead treats the senses “sleepwalker” and “born in the same month” as inherited from Latin and the senses “seeing visions, bizarre” as borrowed from French and Italian.[1]

The Latin adjective is formed on lūna (“moon”) with the suffix -āticus;[9] Scriban explains it by the old belief that moonlight affects the mind.[8]

Earliest recorded meaning

Tiktin's first record is a Gospel text of 1551–1553, at Matthew 4:24, where the sick brought to Jesus include the possessed and the moonstruck.[7] The New Testament of 1648 has lunatec: „Doamne, fie-ți milă de fiiul mieu, că e lunatec și rău pate” “Lord, have mercy on my son, for he is moonstruck and suffers badly”.[4][3]

Semantic evolution

In the old texts the word meant “moonstruck”: epileptic, or out of one's mind, and boală lunatică was epilepsy.[4][3] Later it came to mean a sleepwalker, and in the 19th century, in Alecsandri and Eminescu, also someone who sees visions or is easily frightened, then anything unreal, fantastic or bizarre.[4][10]

A popular sense is “born in the same month as another”: folk custom held that a girl and a boy born in the same month should not marry.[7][2] The western form lunatec is the older spelling;[8] Scriban gives lunatic as the eastern form.[8][4]
