Pronunciation

  • Classical: [tanˈtʊm.mɔ.dɔ][1]
  • Ecclesiastical: [tanˈtum.mo.do][1]

Forms

tantummodo (not comparable)[1]

Etymology

It is from Latin tantum (“so much; only”) + modo (“only”).[1][2] The adverb modo is a derivative of modus (“measure”),[3] which de Vaan traces to Proto-Italic *medo- (“measure, judgement”) and Proto-Indo-European *med-o- (“measure”).[3]

Earliest recorded meaning

Köbler's first source is Cicero,[2] who says that people commonly measure the year only by the return of the sun.[4]

Semantic evolution

It means only or merely;[4] Lewis & Short note that it is frequent and Classical, whereas solummodo is only post-Augustan.[4] Caesar uses it of foot soldiers who stood out of the water only with their shoulders, and Horace has “you have only to wish it”.[4] With a negative and sed it means “not only … but”, as in Cicero and Livy.[4] Church Latin glosses it “only, merely, alone”,[5] and Köbler records it in medieval law codes and charters.[2]

Timeline

  • 81–43 BC – Cicero of measuring the year only by the sun.[4][2]
  • c. 50 BC – Caesar of soldiers standing out of the water.[4][2]
  • 65–8 BC – Horace of having only to wish.[4][2]
  • 59 BC–17 AD – Livy in “not only … but”.[4][2]
