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]
