Inherited from
Proto-Italic *dūro-

Pronunciation

  • IPA (Classical): [ˈduː.rʊs][1]
  • IPA (Ecclesiastical): [ˈduː.rus][1]

Forms

dūrus (feminine dūra, neuter dūrum, comparative dūrior, superlative dūrissimus, adverb dūrē or dūriter); first/second-declension adjective[1]

Etymology

It is inherited from Proto-Italic *dūro-, and de Vaan derives it from Proto-Indo-European *du(e)h₂-ro- (“far, long”), with a shift from “lasting long” to “hard”; the verb dūrō “to harden, last” bridges the senses.[2][1] Cognate on this view with Sanskrit दूर (dūrá, “far, long”) and Ancient Greek δηρός (dērós, “long”), though Wiktionary notes the semantic problems.[2][1] The Oxford Latin Dictionary and the Thesaurus prefer *drū-ros, related to Old Irish dron (“firm”), Old English trum (“firm, strong”) and Sanskrit दारुण (dāruṇá, “hard, harsh”).[3][4]

Earliest recorded meaning

Plautus uses it.[2] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

In Classical Latin it was hard to the touch, firm or solid, as Lucretius' hard iron, and harsh to the taste, as Cato's dark harsh wine.[3][6] Of people it meant hardy and robust, as Cicero's brave and hardy Spartans, unfeeling or stubborn, harsh and pitiless, as Terence's strict father, and austere.[3]

In medieval Latin it kept the senses “hard, firm”; in music it was used of a note that is not softened, and in anatomy of the dūra māter, the outer membrane of the brain.[7] It survives as Italian duro, French dur, Spanish duro and Romanian dur.[1] English dour probably comes directly from it.[8]

Timeline

  • c. 250–184 BC – Plautus uses it.[2][5]
  • 190–159 BC – Terence has a father say he was harsh enough.[3][5]
  • mid-14th century – English dour is recorded in Scots and northern English.[8]
