Lisbon

As the capital of Portugal, from French Lisbonne, from Arabic لِشْبُونَة (lišbūna), from Latin Olisīpō, the origin of which is uncertain. Older spellings include Ulixbona and Ulixbuna (in the Visigothic era); Ὀλισσιπών (Olissipṓn) or Ὀλισσιπόνα (Olissipóna) (by Greek writers), Olisippo (by Pliny the Elder), and Ulyssippo (by Pomponius Mela of Hispania), the last of which relates to the first-century Roman folk etymology that it was founded by and named after Ulysses; another common folk etymology is the Phoenician 𐤏𐤋𐤉𐤑 𐤏𐤁𐤀 (ʿlyṣ ʿbʾ /⁠ʿaliṣ-ʿuboʾ⁠/, “safe harbour”), but there is not much evidence for such words. Another possibility, based on hydronymy of the area, derives the name from Paleo-Hispanic's appellation for the Tagus, Lisso or Lucio.
