“In English, ‘Kerguelen’ is pronounced [‘kə:gɪlɪn], [‘kɚgələn], etc.” Wikipedia
I can hardly think of anything to say. I’ve been all wrong. And I guess the only worthwhile question left to ask is … well … uh … how do you pronounce ‘kə:gɪlɪn or ‘kɚgələn?
P.S. Read Why Kerguelen? for an explanation as to my fascination with the island(s).
