castello

Forms

castello m (plural castelli or (Old Italian) castella)^[1] Old Italian also had a feminine plural castella, common in early texts.^[2][3] Northern Old Italian forms include castelo and castel, and Old Bergamasque had the plural castey.^[4]

Etymology

It is inherited from Latin castellum (“fortified settlement, fort”), a diminutive of castrum (“fortified place”).^[2][5][6][1] The learned word castro continues the base noun.^[2][5]

The Latin word lives on in all the Romance languages except Romanian: French château, Occitan castel, Catalan castell, Spanish castillo, Portuguese castelo, Sardinian casteddu and Romansh chastè.^[5][4][7] It also passed into the Germanic languages and into Insular Celtic, and Byzantine Greek borrowed it as Ancient Greek κάστελλον (kástellon).^[8]

According to de Vaan, castrum first meant a part cut off, then a fenced property and finally a camp.^[9] He traces it to Proto-Italic *kastro- (“part, share”), perhaps from Proto-Indo-European *ḱes- (“to cut”), the root that also gave castrō (“to castrate”).^[9]

Earliest recorded meaning

The TLIO's first record is the Cremonese poet Uguccione da Lodi, early in the 13th century, who lists castelo beside roca among the things that cannot save a man at his death.^[10][11] The sense is a fortified building with towers and walls, the residence of a lord.^[2][10]

Semantic evolution

Already before 1294 Guittone d'Arezzo used the word for a village surrounded by walls, the sense still seen in place names such as Castelfranco and the Castelli Romani.^[2][12] By the 14th century it had technical senses taken from its shape: a wooden scaffold, a siege tower pushed against enemy walls, a tower on an elephant's back, and the raised structure at the bow of a ship.^[2][10] The naval sense was shared by all the Mediterranean fleets, and German took it as Castell in 1479.^[8][13]

Later the word named many frames and supports: the scaffolding of builders, the frame of a crane or a mine shaft, the body of a revolver and the case of a watch's works.^[6][12] Letto a castello, “bunk bed”, and castello di carte, “house of cards”, also used of any plan with no firm basis, are common phrases.^[6][14] Fare castelli in aria means to dream of impossible things, and the poet Passeroni wrote of castelli in Ispagna in the same sense.^[15][16]
