Lewis & Short

Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

plĕo, ēre, v. n., to fill, to fulfil, the root of plenus, q. v., compleo, expleo, suppleo: plentur antiqui etiam sine praepositionibus dicebant, Fest. p. 230 Müll.

plērus, a, um, adj. [root ple-, v. plenus], very many, a very great part, most (anteclass. prim. form, for the class. plerusque, plerique): ager, campestris plerus, for the most part, Cato ap. Prisc. p. 668 P.: pater Achaeos in Caphareis saxis pleros perdidit, Pac. ib.: plera pars, id. ib. and ap. Fest. p. 230 Müll.: minores magistratus partiti iuris ploeres in ploera sunto, Cic. Leg. 3, 3, 6.
Neutr. adverb.: plerum (like plerumque, v. plerusque), for the most part, mostly, commonly: fieri solet plerum, ut, etc., Asell. ap. Prisc. p. 668 P.
