Pronunciation

  • Classical: [ɪŋ.kʷɪˈliː.nʊs][1]
  • Ecclesiastical: [iŋ.kʷiˈliː.nus][1]

Forms

inquilīnus m (genitive inquilīnī, feminine inquilīna); second declension[1] Lewis and Short also give an adjective inquilīnus, -a, -um.[2]

Etymology

It is from Latin in- (“in”) + colō1 (“to inhabit”) + -īnus,[3][1] built on an old stem ⟨*quil-⟩ of the verb rather than on ⟨col-⟩.[3] De Vaan notes that the word is not recorded before Cicero; if it is old, it shows a Proto-Italic /kʷe/ becoming /kʷi/ before a palatal /l/, instead of the change to /kʷo/ seen in the verb.[4] Wiktionary reconstructs Proto-Italic *enkʷilīnos.[1] Lewis and Short and Etymonline explain it instead as standing for ⟨*incolīnus⟩, from incola “inhabitant”;[2][5] the TLL also derives it from that noun, like ⟨Esquilīnus⟩, and reports Leumann's view that vīcīnus “neighbour” influenced its meaning.[6]

Earliest recorded meaning

Köbler and the OLD find it first in Cicero,[7][3] who in the Second Philippic says that while his opponent was the tenant of a house, not its owner, the whole place rang with the voices of drunkards (tē inquilīnō, nōn enim dominō).[3][2]

Semantic evolution

The word named someone living in a place that was not his own, especially a lodger or tenant beside the owner (dominus):[2][8] Suetonius speaks of the tenants of private houses and blocks of flats, and Seneca and Martial of a lodger in the same house.[2][8] More generally it meant an inhabitant, as of the dwellers of a village on the Po in Pliny the Elder, and Ammianus calls some men the permanent inmates of the prisons.[3][2][8]

It was easily turned to scorn: Sallust reports Cicero being called an inquilīnus cīvis urbis Rōmae, a citizen who was a mere lodger in Rome, since he was not born there.[2][8][9] Seneca calls students who attend lectures without learning anything “lodgers, not disciples”, Varro has vices moving in as lodgers, and Tertullian makes the soul the lodger of the flesh.[2][9] Roman law used it of a kind of serf, perhaps at first a barbarian settled on Roman land.[3]

Medieval Latin used it for a foreigner and for a free tenant or cottar;[10] British lawyers distinguished the inquilīnus who rents a house in town from the colōnus who farms the land.[11] It survives in Italian inquilino “tenant”.[9] English inquiline meant “lodger” from the 1640s and took its zoological sense, an animal living in another's dwelling, in 1865.[5]
