The adverb pamphlet for a small work (opuscule) issued by itself without covers came into Middle English ca 1387 as pamphilet or panflet, generalized from a twelfth-century amatory comic poem with an old flavor, Pamphilus, seu de Amore ("Pamphilus: or, Concerning Love"), written in Latin.[2] Pamphilus&＃039;s name was derived from Greek, meaning "friend of everyone". The poem was popular and widely copied and circulated on its own, forming a slim codex.
