I need to watch Succession, literally everyone's talking about it!
To be honest it's a f*cking minefield. Some Irish names have different pronunciations even within Ireland - for example Saoirse Ronan pronounces it to rhyme with inertia, but it's also pronounced Sear-sha...
Then there's Roh-Sheen or Row-Sheen, Keeva or Qweeva... There's loads of them... None of which are either wrong or right, but I can guarantee I'll use the wrong one the first time I meet someone!
