Pronunciation

  • /ˈseʝo/, [ˈse.ʝo], /ˈseʎo/[1]

Forms

sello m (plural sellos)[1] The usual early form is seello, at times siello; it was reduced to sello by the 14th century, though seello still appears in the archaic style of the Rimado de palacio.[2] Old Spanish texts also have seyello, siyello and sieyllo.[3][4]

Etymology

It is inherited from Old Spanish seello, inherited from Latin sigillum (“small figure; mark; seal”).[2][5][6][1] The Latin noun is a diminutive of signum (“sign, mark”).[5][7][1] Wiktionary reconstructs its earlier form as *signolom.[1] The Latin word meant “statuette” and “sign, mark” as well as the impression of a seal and the seal itself.[2][7]

The word is found in all the Romance languages: Portuguese selo, Galician selo, Catalan segell, French sceau and Italian suggello.[2][4][8] The French form goes back to a popular variant *sigellum.[9]

Its learned doublet is sigilo, which Lope de Vega used for “seal” and which took on the sense “secrecy”, as if a matter were kept under seal.[2][5]

Earliest recorded meaning

Corominas first finds it in Berceo's Milagros (1220–1250): ponga y su seiello a la postremería “let him put his seal at the end”.[2][5] The CDH has earlier records in charters: about 1218 a donor orders mio seello pendente “my hanging seal” to be put on the deed, and the Fazienda de Ultra Mar (c. 1200, in a 13th-century copy) has seyello.[10]

Semantic evolution

In the Middle Ages the word named the seal with which charters were authenticated, often hanging from the document, and its impression.[10][11] Covarrubias in 1611 notes the phrase echar el sello “to conclude a business completely” and the plant sello de Salomón.[12] Autoridades adds the house where documents were sealed.[13]

The adhesive paper stamp entered the Academy's dictionary by 1884, and the postage stamp is now the word's first everyday sense.[14][6][15] The Castilian word spread into Catalan in the 19th century with the postage stamp, until writers brought back the native Catalan segell.[16] In several South American countries sello is the reverse of a coin, as in cara o sello “heads or tails”.[6][17][1] Tagalog and Cebuano borrowed it as selyo.[1]
