capāx (genitive capācis, comparative capācior, superlative capācissimus); third-declension one-termination adjective[1]
Etymology
It is from Latin capiō (“to take, hold”) + -āx.[2][1] The verb capiō is inherited from Proto-Italic *kap-i- (“to seize”), which de Vaan derives from PIE *kh₂p-i- or from a non-Indo-European *kap-i-.[3]
Earliest recorded meaning
De Vaan dates it from Lucretius,[3] who speaks of the capacious walls of the world.[2] Köbler dates Lucretius 96–55 BC.[4]
Semantic evolution
It meant able to hold a lot, roomy or capacious, as of cups, urns and places.[2] Lewis and Short note that it is frequent in poets and in post-Augustan prose, and that Cicero perhaps has it only once, figuratively.[5] With a genitive it meant big enough for something, then capable of having or receiving, and capable of understanding.[2]
In medieval British Latin it also meant retentive.[6] It survives in Italian capace and Spanish capaz, and English capacious dates from the 1610s.[1][7]
