Forms
sono m (plural sonos)[1] Houaiss records sono, sonno and sõo in the 13th century, sopno and ssono in the 14th, and somno in the 15th.[2] The Crónica Geral also writes soño.[3]
Etymology
It is inherited from Latin somnus (“sleep”), written Old Galician-Portuguese sono in the oldest texts.[2][4][5][1] Portuguese keeps it apart from sonho “dream”, which comes from somnium (“dream”).[4] Spanish sueño stands for both Latin words, and French sommeil comes from the diminutive somniculus.[2][6]
The same Latin word is Galician sono, Italian sonno and Romanian somn.[1][7] The Latin noun goes back to Proto-Italic *swepnos and Proto-Indo-European *swépnos (“sleep”), from the root *swep-;[1][8] it is cognate with Ancient Greek ὕπνος (húpnos, “sleep”) and Sanskrit स्वप्न (svapna, “sleep, dream”).[1]
Earliest recorded meaning
In the Cantigas de Santa Maria a man falls into tal sono que sempre depois dormira “such a sleep that he would have slept for ever after”, and the monks of another miracle have tan gran sono that they do not wake.[3] A cantiga of Roi Fernandiz de Santiago in the Cancioneiro da Ajuda speaks of sleeping all one's sleep (dormir todo seu sono).[3]
Semantic evolution
The medieval word already meant both the state of sleep and the need for it.[3] The early dictionaries render it by Latin somnus,[9][10] and Bluteau explains sleep as a suspension of the senses caused by vapours rising from the stomach to the brain.[11] Figurative uses make it death (sono eterno, sono dos justos), stagnation, idleness and calm.[2][12]
The word passed into Macanese as sôno and into Ambonese Malay as sono.[1]
