Forms

sēdulitās f (genitive sēdulitātis); third declension[1]

Etymology

It is from Latin sēdulus (“attentive, busy”) + -tās.[2][1][3] De Vaan follows Meiser in deriving the adverb sēdulō “sincerely, diligently” from ⟨*sē dolōd⟩ “without guile”, with dolus (“guile”).[4]

Earliest recorded meaning

De Vaan dates it from Varro, Köbler from Cicero;[4][3] in Cicero's letters Caelius praises Cornelius Balbus' work and assiduity.[5]

Semantic evolution

It is painstaking attention to a task, application, assiduity, zeal;[2][5] Lewis & Short call it classical, with the synonym dīligentia.[2][5] Döderlein describes it as the tireless bustling of a busy housewife, a kind nurse or one who pays officious court, against the loftier industria;[6] Columella speaks of a matron's housewifely diligence.[6] Church Latin glosses it watchfulness.[7]

Timeline

  • 81–43 BC – Caelius in Cicero's letters.[5]
