While the town's name is generally seen as a diminutive form of Barcelona in Spain, Albert Dauzat and Charles Rostaing point out an earlier attestation of the name Barcilona in Barcelonnette in around 1200, and suggest that it is derived instead from two earlier stems signifying a mountain, * bar and * cin ( the latter of which is also seen in the name of Mont Cenis ).

While the cardinalate has long been expanded beyond the Roman pastoral clergy and Roman Curia, every cardinal priest has titular church in Rome, though they may be bishops or archbishops elsewhere, just as cardinal bishops are given one of the suburbicarian dioceses around Rome.
