Forms

dormītōrius (feminine dormītōria, neuter dormītōrium); first/second-declension adjective[1]

Etymology

It is formed from Latin dormiō (“to sleep”) + -tōrius.[1][2][3] Georges derives it from dormītor (“sleeper”).[4]

Earliest recorded meaning

It is first found in Pliny the Elder,[1][3] who speaks of a bedroom (cubiculum dormitorium) and uses the neuter as a noun for a bedroom.[1][5]

Semantic evolution

In Classical Latin the adjective described what was meant or used for sleeping: Pliny the Younger speaks of a sleeping wing (membrum dormitorium), and the jurists speak of a sleeping carriage (carrucha dormitoria).[1][6][4] The neuter dormitorium became a noun for a bedroom,[1] and in Christian Latin also a resting place of the dead.[4]

Medieval Latin kept the adjective for things belonging to sleep[7][8] and used the noun for a dormitory.[7]

Timeline

  • 23/24–79 AD – Pliny the Elder uses it of a bedroom, and the neuter as a noun.[1][3]
