Pronunciation

Forms

tēctum n (genitive tēctī); second declension[1]

Etymology

It is the neuter of tēctus, the participle of tegō “to cover”.[2][1][3] Tegō goes back to Proto-Indo-European *(s)teg- (“to cover”), and is cognate with Ancient Greek τέγος (tégos, “roof”).[3][1]

Earliest recorded meaning

De Vaan dates it from Plautus, whose character says he will climb up onto the roof.[3][2] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It meant a roof, as the roof and tiles blown off a farmhouse in Plautus' Rudens, and a ceiling.[2][5] By extension it meant a roofed building, a house or dwelling, as Ennius' household gods who care for our home.[2][6]

In Medieval Latin it was a roof, ceiling or vault, figuratively the sky, and sub tēctō meant secretly.[7] It survives in Italian tetto, French toit and Spanish techo.[1]
