Forms

pecū̆ n (genitive pecūs or pecū); fourth declension[1]

Etymology

It is inherited from Proto-Italic *peku-, inherited from Proto-Indo-European *peḱ-u- (“cattle”), from the root Proto-Indo-European *peḱ- (“to pluck, fleece”).[2][1][3] Cognate with Umbrian pequo (“cattle”), Sanskrit पशु (paśú, “cattle”), Avestan pasu- (“cattle”), Lithuanian pẽkus, Gothic 𐍆𐌰𐌹𐌷𐌿 (faihu, “property”) and Old English feoh (“cattle, wealth”).[2][4][1] The origin of the long final /ū/ is uncertain.[2] pecus “cattle” is the s-stem from the same root.[2][1]

Earliest recorded meaning

De Vaan dates it from Naevius, who speaks of men, herds and beasts.[2][4] Köbler dates Naevius c. 235–200 BC.[3]

Semantic evolution

In the singular it meant a flock or herd, as Plautus' shepherd who sleeps while his sheep stray bleating from the flock.[4] The plural pecua meant farm animals, livestock, as in Plautus, Cato and Lucretius.[4][5] It was mostly an early word, with a dative pecuī in Lucilius.[5]

From it came pecūnia “money”, probably from an adjective *pecūnus “rich in cattle”, and pecūlium “private property”.[2]
