Pentavryso (Greek: Πεντάβρυσον; Bulgarian and Macedonian Slavic: Зелегоже Zelegože) is a village in the municipality of Agia Triada, in the regional unit of Kastoria, Greece. It is part of the region West Macedonia. Before 1928 and certainly since Rigas Feraios Charta the town's name was Zelegoz. There are some uncertainties as to the actual spelling of the formal name of the town. The old name changes from Zelegoze to Zelegosh or Zelegozde to Zeligozdi, according to the writer or observer. It certainly has a heavy influence from Turkish with some Greek and Latin meanings attached to it. It certainly is a composite word consisting of the word Zele (Greek Ζήλος) changed to Roman Zele, and adopted by the Turks as such, meaning "special", and not jealousy as the same does in modern Greek. The second part of the word, goz or in its variations goze, gozde or gozdi, are all Turkish (Göz) meaning "eye", "view", "outer" "look" and their synonyms. So, the old name of the town Zelegoz most probably means "Special View" or "Special Lookout/Position". This agrees with the geographical position of the town and the strategic place of its geographical and morphological place.
