The spelling of the surname "Raferty" is derived from the Gaelic language. The correct pronunciation is /rəˈfɜːrti/ with the stress on the second syllable. The initial "R" sound is pronounced with a slight trill, and the "a" in the second syllable is pronounced like the "a" in "father". The "f" and "t" sounds are pronounced distinctly, with no blending. The ending "-erty" is pronounced with a long "e" sound and a soft "t" at the end.
