Forms

castelão m (plural castelãos or castelões or castelães, feminine castelã or (rare) castelona or (rare) casteloa, feminine plural castelãs or (rare) castelonas or (rare) casteloas)[1] Old spellings include castelããos (plural, 1297), the feminine castellaa (1309), castelaao, castellão and castellãno.[2][3] Cunha dates castellão to the 16th century.[4] The plural is castelãos, castelões or castelães, and the feminine castelã, with the rare casteloa and castelona.[5][6][1]

Etymology

It is inherited from Latin castellānus (“of a castle, (plural) the garrison of a castle”), written Old Galician-Portuguese castelão in the oldest texts.[3][4][1] The Latin adjective is formed from castellum (“fort, castle”) with the suffix -ānus.[7][1] In Medieval Latin the word was first used for an officer in charge of a castle and then its lord.[8]

The sense “Castilian” is the oldest in Portuguese;[2] Houaiss takes it as an extension of the same Latin word, while Wiktionary derives it from Castella (“Castile”) with the same suffix.[3][1] The usual word for “Castilian” today is castelhano, of the same Latin origin but borrowed from Spanish.[3][1] Lorenzo notes that Machado's first record of it is from 1454.[2]

The same Latin word is Galician castelán, Spanish castellano, Catalan castlà, Occitan castelan, French châtelain and Italian castellano.[9][1]

Earliest recorded meaning

The first Portuguese record, in 1297, is the plural castelããos “Castilians”.[2][3] In the Crónica Geral the word also names the Castilian language: et dizia hũa uoz per arauigo et outra per castelão “and he said it once in Arabic and again in Castilian”.[2] The Miragres de Santiago have the plural castelãos “Castilians”.[2]

Semantic evolution

The manuscript of the Crónica also uses Castelão as a byname of nobles, as in Pero Fernandez o Castelão.[2] The sense tied to the castle appears later: Houaiss dates the adjective “guarding a castle” to 1557 and the noun “governor of a castle in the name of the king or a lord” to 1600.[3] Caldas Aulete defined the castelão as the lord who had the right to fortify his house and to judge within a certain area, and added the black grape grown in the Tagus valley and the Alentejo, also called trincadeira.[5] The sense “Castilian” is now marked as old or dated.[10][1]
