Forms

tantopere (not comparable)[1] Also written separately as tantō opere.[2][3][4]

Etymology

It is from Latin tantus (“so great”) + opus (“work, effort”),[5][6] fused from the ablative phrase ⟨tantō opere⟩, literally “with so much effort”.[1][3] opus goes back to Proto-Italic *opes- (“work”) and Proto-Indo-European *h₃ep-os (“work”).[7]

Earliest recorded meaning

It is found in Plautus, written as two words: “why had you been so very frightened?” (cur tanto opere extimueras?).[2]

Semantic evolution

Terence also uses it,[2] and it is common in classical prose, either as one word or as two.[2][3] Cicero writes si studia Graecorum vos tanto opere delectant, “if Greek learning delights you so much”, and pairs it with a following quantopere or quam, “as much … as”;[2][4][8][9] Caesar has the reverse order, and Cicero and Nepos also use it with a clause of result.[2][4][8][9] A bilingual glossary renders it by Ancient Greek σπουδαίως (spoudaíōs), “earnestly”.[10]

In British medieval Latin it is used, from Gildas and Bede on, with verbs of wishing, care or effort, “so earnestly”, and more generally “to such a degree”.[11]

Timeline

  • c. 250–184 BC – Plautus uses tanto opere as a phrase.[2][6]
  • 190–159 BC – Terence uses it.[2][6]
  • 81–43 BC – Cicero uses it often, as one word or two.[2][4][6]
  • c. 50 BC – Caesar pairs it with quantopere.[4][6]
  • 1st third of the 8th century AD – Bede uses it with verbs of seeking.[11][6]

Meanings

Adverb

  1. So much, so greatly, to such a degree.[2][3][4]
  2. With quantopere, quam or ut: as much (as), so much (that).[4][8]
  3. (Medieval Latin) So earnestly, with verbs of wishing or effort.[11]

Usage notes

Georges notes that the spelling, as one word or two, follows the same rules as for magnopere.[3]
