I'm afraid you're rather missing the point, though, Amorkuz. Opdagon isn't asking how his name is spelled, he's asking how it's supposed to be pronounced (I would, at a guess, wager that Opdagon hasn't seen The Woman Who Fell To Earth yet, came across our page for T'zim Sha, and wants to know how you read it aloud).

By the way, is the thread you linked still… up to date? It's hard to keep track, but I understand that novelisations are no longer "secondary canon" these days, and much of the debate revolved around that fact… (EDIT: After reading more in-depth, I find that there is indeed a mention of the update in the last post, so this question is moot.)

And finally, to answer the question… well, it's simple, isn't it? It's pronounced as close to 'Tim' as possible while still technically being T'zim. So basically "Tsim", with the "s" very faint.
