how do you pronounce her fist name?

SUR-SHA

Sa-oir-se.

That is how to pronounce that sequence of letters.

It's not that difficult, it's clear for the whole continent.
Unless you are an imbecile from one of those islands.
If that's the case, just invent a new rule every time.

SAIR-sha, or so I've been told. It's a really weird Celtic name, like Siobhan (SHOW-bon), or Mairead (mah-REED), or Meav (MAYV).

Weirdest Celtic name I've seen so far is Loghair, which for no reason I can decipher, is pronounced, "LEER-ee."

There are multiple videos of her explaining it. I think even once on the Graham Norton show she did a little rhyme. But from her directly in case you don't trust any of the comments here.

I seriously doubt she has names for her fists. I could be wrong though.

I bet she's bored to fuck being asked about it at this stage.

Watch one of the 4,000 clips of interviews where she was asked this. I'm amazed that she always answers gracefully and doesn't just slap people for asking at this point.
