Confidence
Probable
Formation
Derivation
First attested
81–43 BC, Cicero
Ultimate origin
Proto-Italic (*towē-)

Pronunciation

  • Classical: [ˈtuː.toː][1]
  • Ecclesiastical: [ˈtuː.to][1]

Forms

tūtō (comparative tūtius, superlative tūtissimē or tūtissimō)[1] The superlative is tūtissimē or, in Cicero and Pliny the Elder, tūtissimō.[2]

Etymology

It is formed from tūtus (“safe”) with the adverbial suffix -ō; compare tūtē.[2][1] De Vaan explains ⟨tūtus⟩ as the old past participle of ⟨tuor⟩, tueor (“to watch over, protect”), from Proto-Italic *towē- (“to protect”), and compares Sanskrit तवस् (tavás-, “strong”); the Proto-Indo-European form is uncertain.[3]

Earliest recorded meaning

Köbler gives Cicero as its first author,[4] who tells Catiline that he “cannot in any way be safe within the same walls” as him.[2]

Semantic evolution

It is “without risk of harm, safely, securely”, and tūtō esse is to be in safety somewhere, as in Cicero's speeches and Sallust.[2]

Timeline

  • 81–43 BC – Cicero to Catiline.[2][4]
  • 86–34 BC – Sallust has tūtō esse.[2][4]

Meanings

Adverb

  1. Safely, securely, without danger;[2][1] tūtō esse, to be safe.[2][1]

Usage notes

Tūtō is also a rare first-conjugation verb, a variant of the deponent tūtor, “to protect”.[2][1]
