Word History

Etymology

Noun

Middle English porcioun, porcion "part allotted to a person or institution, share, section into which a thing is divided, quantity", borrowed from Anglo-French porciun, porcioun, borrowed from Latin portiōn-, portiō "ratio, proportion, part, share" (earliest in the phrase prō portiōne "in the degree proper to each, proportionately"), probably by dissimilation from *prōrtiōne, by univerbation and syncope from prō ratiōne "in proportion" (with ratiō "reckoning, calculation, proportion") — more at pro- entry 2, reason entry 1

Note: If correct, this etymology represents the first of two univerbations with the preposition/prefix prō̆, the first with ratiōn- (whence *prō ratiōne > *prōratiōne > *prōrtiōne > portiōn-, portiō), the second with the newly formed noun portiō (whence prō portiōne > *prōportiōne > prōportiōn-, prōportiō—see proportion entry 1). Also suggested is derivation of portiō from partītiōn-, partītiō "sharing out, distribution, division of a speech" (see partition entry 1), assuming *prō partiōne reduced from *prō partītione; however, the noun partītiō is not attested before Cicero, while portiō is used already by Plautus.

Verb

Middle English portionen, porciounen "to divide into portions," borrowed from Anglo-French porcioner, borrowed from Medieval Latin portiōnāre, derivative of Latin portiōn-, portiō "ratio, proportion, part, share" — more at portion entry 1
