Ultimate origin

Pronunciation

  • Classical: [aˈɫʊm.nʊs][1]
  • Ecclesiastical: [aˈlum.nus][1]

Forms

alumnus (feminine alumna, neuter alumnum); first/second-declension adjective[1] Pacuvius has the old genitive plural alumnum.[2][3]

Etymology

It is inherited from Proto-Italic *alomnos, inherited from Proto-Indo-European *h₂el-o-mh₁no- (“being fed”), the middle present participle of Proto-Indo-European *h₂el- (“to nourish, grow”), the root of alō (“to nourish”).[4][1] Its ending is the participial suffix seen in Greek -μενος (-menos).[2][5] De Vaan gives as cognates of the root Old Irish alid (“feeds”), Gothic 𐌰𐌻𐌰𐌽 (alan, “to grow up”) and Ancient Greek ἄναλτος (ánaltos, “insatiable”).[4]

Earliest recorded meaning

De Vaan dates it from Plautus,[4] whose Mercator has “I am your master and your foster-son”.[2]

Semantic evolution

As a noun it is a nursling or foster-child, in contrast with a natural son, and in the poets a young animal or plant.[2][3] It also means a person considered as the product of a country or place, as in Cicero's Italy seeing her own son crucified; a ward or protégé (Curtius); and the pupil or follower of a philosopher, as Aristotle and the others are Plato's.[2] As an adjective it means “reared, fostered”, and in Statius “native”.[2][3]

Church Latin glosses it “pupil, student, one brought up”.[6] In medieval sources it can mean a client kept in a lord's household, and also a teacher.[7]
