Pronunciation

  • Classical: [tae̯.diˈoː.sʊs][1]
  • Ecclesiastical: [te.diˈɔː.s̬us][1]

Forms

taediōsus (feminine taediōsa, neuter taediōsum); first/second-declension adjective[1] The medieval spelling tediosus is also found.[2]

Etymology

It is formed from Latin taedium + -ōsus, “full of weariness”.[1][3][2] The noun taedium (“weariness, disgust”) belongs to the impersonal verb taedet (“it wearies”),[2] which de Vaan traces to Proto-Italic *taid-ē-.[4]

Earliest recorded meaning

It is a Late Latin word:[5][6] the earliest author the dictionaries cite is Arnobius (297–310 AD), who uses it in the sense “tiresome, irksome”.[2][6]

Semantic evolution

In the 4th century Firmicus Maternus and Ambrose use it of what is wearisome or burdensome,[7][3][8] and it also appears in an inscription.[3] Medieval Latin kept the sense “tedious, boring” and added “sad, low-spirited” and “weary, disgusted”, so that it could describe the person as well as the thing that wearies;[9][5] British writers also used it for someone easily tired or slothful.[5] Humanist authors went on using it for what is dull to tell or to hear.[10] Through Old French it gave English tedious.[11]

Timeline

  • 297–310 AD – Arnobius uses it for what is irksome.[2][6]
  • 343/350 AD – Firmicus Maternus calls life a wearisome burden (taediosa sarcina lucis).[7][2]
  • c. 340–397 AD – Ambrose uses it in his treatise on duties.[3][2]
  • early 15th century – English tedious is recorded, from Old French tedieus and ultimately from this word.[11]
  • 1492 – Perger uses tediosum in a letter for what is tiresome to bear.[10]
