Pronunciation

  • Classical: [ˈdɛ.kɪ.ma][1]
  • Ecclesiastical: [ˈdɛː.t͡ʃi.ma][1]

Forms

decima f (genitive decimae); first declension[1] It is also spelled decuma.[2][3]

Etymology

It is from Latin decimus (“tenth”), in its feminine form,[2][1] used as a noun by ellipsis of pars “part” or hōra “hour”.[1][4][3] De Vaan treats it under decem: the ordinal goes back to Proto-Italic *dekamo- (“tenth”), which gave ⟨decumo-⟩ or ⟨decimo-⟩.[5]

Earliest recorded meaning

De Vaan records it from Plautus on;[5] in the Stichus (c. 250–184 BC) it is a tithe offered to Hercules.[2][6]

Semantic evolution

Its first sense was a tenth part, especially a tenth vowed to a god such as Hercules or Apollo.[2][4] It then named the tax of a tenth on the produce of provincial land, or the right to collect it, which Cicero discusses at length in the speeches against Verres;[2][3] a tenth of an estate, given by will;[2][3] and a distribution of money or food to the people.[3] With hōra understood it was the tenth hour of the day, counted from dawn.[2][4]

In Christian and medieval use it became the church tithe, a tenth of income and above all of farm produce, given at first voluntarily and made compulsory in the Carolingian period; it also meant the right to levy tithes and the area that paid them.[7][8] English dime “a tenth, tithe” comes from it, partly through Old French.[9]

Usage notes

Decima (also Decuma) was also the name of a Roman goddess of the last month of pregnancy, counted as one of the three Fates;[2][10][3] Varro, quoted by Gellius, derives her name from the time of a timely birth.[2][10][3]
