Forms

ēmptiō f (genitive ēmptiōnis); third declension[1] It is also spelled emtio.[2]

Etymology

It is from Latin emō (“to buy”) + -tiō, formed on the participle stem ⟨empt-⟩.[3][1][4] De Vaan traces emō, first “to take”, to Proto-Italic *eme/o- (“to take”) and Proto-Indo-European *h₁em- (“to take”).[5] Cognate with Oscan emmens (“they have bought”), Old Irish ar·foím (“to receive”) and Lithuanian im̃ti (“to take”).[5]

Earliest recorded meaning

Köbler dates it from Cicero,[6] who in the Pro Roscio Amerino calls a purchase of goods scandalous.[3]

Semantic evolution

It means the act of buying, a purchase, and by extension the thing bought, as when Cicero writes that he wants none of those purchases.[3][2] In law it is the contract of purchase: Gaius and Justinian's Institutes treat emptio et venditio, purchase and sale, and the jurist Scaevola uses it of a deed of purchase.[2][3]

Church Latin keeps purchase or buying.[7] In medieval Latin it can mean the thing bought, or the fee paid when a holding changed hands.[8] English borrowed emption in the late 15th century.[4]
