pamphlet

The noun is derived from Late Middle English pamflet, pamphilet (“short written text; small book; tract”) [and other forms], from Middle French Pamphilet (compare Late Latin (Anglo-Latin) pamfletus, panfletus, paunflettus (“short written text”), Old French Panfilès), a popular shorthand for the 12th-century Latin love poem Pamphilus, seu de amore (Pamphilus, or On Love): the widely circulated pamphlets then gave this name to the whole phenomenon. Pamphilet is derived from Latin Pamphilus, the name of a protagonist of the poem + Middle French -et (suffix forming diminutive masculine nouns); while Pamphilus is from Ancient Greek Πάμφιλος (Pámphilos, literally “beloved by all”), from παν- (pan-, prefix meaning ‘all; every’) (ultimately from Proto-Indo-European *peh₂- (“to protect; to shepherd”)) + φῐ́λος (phĭ́los, “beloved, dear”) (ultimately from Proto-Indo-European *bʰil- (“decent; friendly; good; harmonious”)).

For the Middle French and Old French use of the suffix -et to form shorthands for the titles of works, compare Middle French Avionet (“the fables of Avianus”) from Avianus; Middle French Catonet, Old French Chatonnet, Chatonez (“the Distichs of Cato”) from Caton (they were formerly believed to be by Cato); and Old French Esopet, Isopet (“Aesop’s Fables”) from Ésope (Aesop).

The verb is derived from the noun.
