tueor (present infinitive tuērī, perfect active tuitus sum); second conjugation, deponent[1]
Etymology
The origin is uncertain.[1][2] De Vaan reconstructs Proto-Italic *-tow-ē- (“to protect”), perhaps from a causative Proto-Indo-European *touh₂-eie-, and thinks the first meaning was “to watch over, protect”, which became “to look at”.[3] This would connect it with the root *tewh₂- “to be strong”, as in Sanskrit तवस् (tavás, “strong”).[1][3] The old participle tūtus belongs to the variant tuor, the source of tūtor “guardian”.[3]
Earliest recorded meaning
De Vaan dates it from Plautus.[3] Ennius and Lucretius have the third-conjugation form tuor.[3][2] Köbler dates Plautus c. 250–184 BC.[4]
Semantic evolution
In poetry it meant to look at or view, as in Ennius.[2] In prose its usual senses were to protect people from danger, to guard a position in war, to defend someone's interests, to maintain or keep something in good order, to support people with food, and to look after or have charge of something.[2]
Döderlein contrasts tuērī, guarding against a possible danger, with dēfendō, defending against an actual attack, and links it with the guardianship of minors by a tūtor.[5] Its derivatives include tūtus “safe”, intueor “to look at”, tuitiō “protection” and tūtor; English tutor and English tuition come from the last two.[6]
