Valladolid

Valladolid (a province of Castile and León, Spain; capital: Valladolid); Valladolid (a city in Valladolid, Spain)

Attested in 11th century Latin documents in forms such as Valleolide and Valledolidi. The beginning corresponds to valle (“valley”) and the ending seemingly to Olid, a known adaptation of the Arabic name لوليد (Walīd). The additional /-d-/ would in that case represent a possessive (de).
