dormio

Etymology and origin of the Latin word dormio

Pronunciation

  • IPA (Classical): [ˈdɔr.mi.oː][1]
  • IPA (Ecclesiastical): [ˈdɔr.mi.o][1]

Forms

dormiō (present infinitive dormīre, perfect active dormīvī or dormiī, supine dormītum); fourth conjugation, impersonal in the passive[1]

Etymology

It is inherited from Proto-Italic *dormje/o-, inherited from Proto-Indo-European *dr̥m-yé- (“to sleep”).[2][1] De Vaan notes that the roots *drem- and *dreH- both mean “to run” and “to sleep”, the second sense being found for *drem- only in Latin and Slavic.[2]

Cognate with Old Church Slavonic дрѣмати (drěmati, “to doze”), Russian дремать (drematʹ, “to doze”), Sanskrit द्राति (drāti, “sleeps”) and Ancient Greek δαρθάνω (darthánō, “to fall asleep”).[2][3][1]

Earliest recorded meaning

It is found from Plautus onwards,[2][4] who has a character told to go to bed answer dormio “I am asleep, don't shout”.[5][3]

Semantic evolution

Besides sleeping, it meant to behave as if asleep, to be idle or inactive, as when Cicero attacks a consul who sat “dozing” in a crisis.[3][5] In poetry it took an object of time, as in Catullus' “one everlasting night must be slept”.[3][6] It also stood for the sleep of death, especially in Christian epitaphs.[5][7] Cicero's non omnibus dormio “I do not sleep for everyone” meant “I am not blind to everything”.[5][6]

It survives as French and Spanish dormir and Italian dormire,[1] and its derivative dormitorium gave English dormitory, while the participle gave English dormant through French.[8]

Timeline

  • c. 250–184 BC – Plautus uses it for sleeping.[3][4]
  • 234–149 BC – Cato uses the future dormibit.[3][4]
  • 81/79–52/50 BC – Catullus writes of one everlasting night to be slept.[3][4]
