What does alcaide mean?
An alcaide is the governor, keeper, or warden of a castle, fortress, or prison, a title used historically in Spain and Portugal. The word entered European languages from Arabic during the centuries of Muslim rule in Iberia, deriving from al-qā'id, meaning 'the commander' — the same Arabic root that gave Spanish its alcalde (mayor) and alcázar (fortress). In practice, an alcaide was the officer entrusted with a stronghold's defense and its keys, answerable to the crown; in later usage the title also came to denote the keeper of a prison, making it a familiar figure in accounts of Golden Age Spain. Today the word survives almost exclusively in historical and literary contexts — histories of Moorish Spain, studies of medieval fortification, and translations of writers such as Cervantes. Its rarity gives it a distinctly archaic flavor, but for readers of Iberian history it remains an indispensable term for the men who commanded the great castles of Spain and Portugal.
nounA historical term for the governor, keeper, or warden of a castle, fortress, or prison in Spain and Portugal; by extension, the commander of such a stronghold.
- The governor or warden of a castle or fortress in Spain or Portugal.
- The keeper or jailer of a prison, especially in historical Spanish and Portuguese contexts.
"The alcaide of the fortress refused to surrender the keys until the king himself arrived at the gates."
"The alcaide of Toledo's fortress was answerable directly to the crown."
"In Cervantes's Spain, the alcaide of a prison held considerable power over his captives."
The plural follows standard English formation; the original Spanish form is also sometimes retained as 'alcaldes'-style borrowings, but 'alcaides' is the normal English plural.
"The alcaides of the frontier castles met to coordinate the defense of the border."
Borrowed straight from Arabic during eight centuries of Moorish Spain, 'alcaide' literally means 'the commander' — the man who held the keys to the kingdom's castles.
