París m. (Noun) "Paris"
Reduction of the original name in Late Latin, Lutetia Parisiorum "Lutetia of the Parisii." The city's true name was Lutetia (or as recorded by Strabon Λουκοτοκία (Loukotokía)), of unknown origin, and was the chief hub of the Parisii. Matasović (2014) identifies Lutetia as the "mud-town," from Proto-Celtic *lutu- "mud," and ultimately from Proto-Indo-European *leu-to- 'id.' The Parisii were a Celtic tribe conquered by Julius Cæsar during the uprising of Vercingetorix. Like Lutetia, their name is of unknown origin.
parque m. (Noun) "park"
Early 17th cent. Borrowed from French parc "park," but in Old French meaning "enclosure." From Medieval Latin parcus 'id.' Borrowed from a Germanic source (compare Old English pearroc "enclosure"). From Proto-Germanic *parruka- 'id.' An enclosure made of beams. From earlier *(s)porH- "beam." A regional innovation in a very late form of Proto-Indo-European, presumably borrowed from an outside source.

parque m. (Noun) "park, garden;" "enclosure for munitions," "enclosure for military vehicles"
Early 17th cent. Borrowed from French parc "park," "enclosure," "game preserve." From Late Latin parricus 'id.' The natively-inherited word in Spanish is parra (1).
parra (1) f. (Noun) "grapevine"
8th cent. The only convincing etymology is from Late Latin parricus "enclosure" which was borrowed from Gothic *parra 'id.' (Mason 1979; Corominas 1991). This is supported on the basis of cognates in nearby Romance tongues (cf. Occitan parran "orchard," French parc "enclosure"). An older theory of an origin in Basque has been thoroughly rejected (Dworkin 2014).
Also the origin of La Parra, the name for towns in Badajoz, Cuenca, and Toledo; Las Parras, a province in Teruel; and Las Parras de Castellote, a province in Zaragoza.
