Reconstruction

Ringe and Taylor reconstruct the adjective *sikur "secure, safe" for Proto-West Germanic, with the masculine nominative plural *sikurē,[1] and Wiktionary has the same form.[2]

Etymology

It is borrowed from Latin sēcūrus (“without worry, tranquil, secure”).[3] Ringe and Taylor count it among at least two Latin adjectives that might have been borrowed into Proto-West Germanic, the other being *sūbrī "sober, chaste, clean", from sōbrius (“sober”).[3] Holthausen, Berr and Köbler also derive the daughters' words from the Latin adjective.[4][5][6]

Morphology

An adjective.[3] Its first syllable is light, so Old English had no syncope in its inflected forms: *sikur, *sikurē became sicor, sicore.[1]

Evidence

The adjective is attested as Old English sicor, Old Frisian sikur, Old Saxon sikor and Old High German sihhur.[3] The Heliand has the forms ⟨sikur⟩, ⟨sicor⟩, ⟨sicur⟩ and the accusative ⟨sicoran⟩.[6] Old Frisian also has siker, with a weakened second vowel.[7]

Competing analyses

Ringe and Taylor place the loan in Proto-West Germanic,[3] while Boutkan and Siebinga set up a Proto-Frisian *sikur borrowed from the Late Latin form sicurus, and list the Old English, Old Saxon and Old High German words beside it.[7]

Meanings

  1. secure, safe[1][2]
  2. sure, certain[2]

Old English used the word for "secure, certain",[3] Old Saxon also for "free (from guilt)",[5] Old Frisian for "not guilty", "reliable" and "undisputed",[7][8] and Old High German for "carefree", "fearless" and "free from".[9]

Derivatives

  • *sikurōn "to make secure", which Wiktionary reconstructs;[10] Boutkan and Siebinga list the verbs Old Saxon sikoron, Old High German sihhorōn and Old Frisian sikuria.[7]

Reflexes

  • Old English: sicor (“secure, certain”)[4]
  • Old Frisian: sikur (“free of guilt, reliable, undisputed”)[7][8]
  • Old Saxon: sikor (“sure, free (from guilt)”)[5]
  • Old High German: sihhur (“secure, carefree, fearless, free from”)[9]
