Sanskrit purvi "much," prayah "mostly;" Avestan perena-, Old Persian paru "much;" Greek plethos "people, multitude, great number," polys "much, plenty," ploutos "wealth;" Lithuanian pilus "full, abundant;" Old Church Slavonic plunu; Gothic filu "much," Old Norse fjöl-, Old English fela, feola "much, many;" Old English folgian; Old Irish lan, Welsh llawn "full;" Old Irish il, Welsh elu "much"); probably related to root *pele- (2) "to spread."
