Calladine - how do you pronounce this?

[Nutbutter]

to settle an argument - last syllable like come dine with me or to rhyme with Catherine? Or are both acceptable?

(As first name)

This may not be relevant, but so far as I know, similar surnames such as Cannadine are pronounced to rhyme with 'wine'. You can hear one example here: www.c-span.org/video/?195750-1/after-words-david-cannadine

Calla-dine (have a couple of friends with this surname & that’s how they pronounce it)
Caladin would work if they are adamant on the name & looks more boyish than the double-l and -ine

I'd assume transferred surname and say calla-dyne (unless told it was calla-deen). I'd find other pronunciations a little forced/odd

Does it not remind of Calamine lotion? I just think ‘itchy chicken pox’

I'm Scottish and never heard of it. But I'd pronounce it Calla-DINE.

The Calladin (possibly Caladin?) I know pronounces it quite like Catherine: CAL-a-din, with the 'din' to rhyme with 'tin'.

It’s a Scottish surname afaik

Not one I've ever come across in my entire life of living in Scotland.

Would assume it is said to rhyme with Ballantine. - tyne at the end and not teen.

But it screams "made up name" to me.

As a surname, Cal-a-dine. If it was a first name I'd guess Cal-a-deen

Are they maybe thinking of the name Caledon?

It’s the full name of Cal, the baddie in Titanic
