Pronunciation

  • Classical: [ʊn.dʊˈɫaː.tʊs][1]
  • Ecclesiastical: [un.duˈlaː.tus][1]

Forms

undulātus (feminine undulāta, neuter undulātum); first/second-declension adjective[1]

Etymology

It is formed from Latin unda (“wave”) + -ula + -ātus2,[2] that is, from an unattested diminutive *undula (“little wave”) with an adjective suffix.[1]

Earliest recorded meaning

It is first found in Varro, in a passage quoted by Nonius Marcellus and cited also by Pliny the Elder, of togae undulatae, togas patterned with waves like watered fabrics.[3][4]

Semantic evolution

The OLD defines it as having a wavy form, perhaps meaning full and billowing,[2] while Lewis and Short take it as marked with waves, like watered stuffs.[3] It remained a rare word;[5] Stelten lists it in the sense “wavy, undulated”.[5]

  • 23/24–79 AD – Pliny the Elder cites Varro's phrase.[3][4]
