Pronunciation

Forms

sonho m (plural sonhos)[1] Old Galician-Portuguese also wrote sonno;[2][3] Houaiss records soño in the 14th century and ssonhos in the 15th.[2][3]

Etymology

It is inherited from Latin somnium (“dream”), written Old Galician-Portuguese sonho in the oldest texts.[3][2][1] The same Latin word is Galician soño, Italian sogno, French songe and Catalan somni.[4][1] In Spanish, Spanish sueño merged the Latin word with somnus (“sleep”), and means both “sleep” and “dream”;[3][5] Portuguese keeps the two apart, with sono for “sleep”.[3][5] For the ordinary dream, French rêve is the usual word.[3]

The Latin noun is derived from the word for “sleep”, which de Vaan traces to Proto-Indo-European *swépnos (“sleep”), the source also of Sanskrit स्वप्न (svápna, “sleep, dream”) and Ancient Greek ὕπνος (húpnos, “sleep”).[6][7][1] The word for “dream” may continue an old derivative, comparable with स्वप्न्यम् (svápnyam, “vision in a dream”) and Old Church Slavonic съниѥ (sŭnije), or be a Latin formation.[7][1]

Earliest recorded meaning

Houaiss dates the noun to the 13th century from Cunha's records, and Cunha has both sonho and sonno in that century.[3][2] A cantiga warns per sonho, mui gran vergonça averedes, “in a dream, you will have great shame”.[8]

Semantic evolution

Bluteau (1712–1728) defines it as what is pictured to the imagination in sleep, and quotes Vieira on dreams as a mute painting of a person's cares and desires.[9] Morais (1789) adds the figurative sense, something imagined that has no reality.[10] Later senses are a daydream, a vain hope, and a cherished ambition: o sonho dele é viajar.[3][11]

Morais's edition of 1813 records sonhos as a light pastry of flour and eggs fried in butter and dipped in syrup.[12] They are a traditional Christmas sweet; in Brazil sonho is also a filled doughnut, the Berliner (bola-de-berlim).[3][1]
