Pronunciation
Forms
seixo m (plural seixos)[1] An older spelling is seyxo.[1][2]
Etymology
It is inherited from Latin saxum (“rock, boulder”), first recorded in the 14th century.[3][4][1]
The same Latin word is Galician seixo, Italian sasso and Old Leonese sejo (“stone”).[5][6][1] Elsewhere in Romance the Latin word was largely replaced by petra.[5]
The origin of the Latin word is uncertain.[7][1] It goes back to *saksom.[1][7] Some link it with the root Proto-Indo-European *sek- (“to cut”) of secō and with Germanic words for “knife” such as Old High German sahs.[8][1] De Vaan rejects the link with the root, because it leaves the ⟨a⟩ of the Latin word unexplained.[7]
Earliest recorded meaning
Houaiss dates the word to the 14th century, as a hard stone or a fragment of rock.[3] Cardoso translates it in 1569 with Latin saxum.[9]
Semantic evolution
Bluteau defines it in 1712 as a rough and very hard stone, and Morais adds that it may be of any size, from a cornerstone to a large boulder.[2][10] The modern sense is a fragment of rock rounded by water, a pebble, and geologists use the word for particles between 4 and 64 millimetres.[3][1] Small round stones used to decorate gardens and paths are also seixos.[3]
In popular and children's speech the word means a bird's egg in the nest.[3][11][12] In north-eastern Brazil it came to mean a debt left unpaid to a prostitute, and then any unpaid debt or swindle, with passar seixo “to leave without paying”.[3][13]
