How many syllables in 'diamond'

[Aparecium]

I'm in SE England and always say it in two syllables: DI-mond. But I've just been listening to an audiobook read in a very RP accent, and every character gives it three syllables: DI-a-mond. The a is more of a neutral shwah sound than a flat a.

AFAIK I speak RP with a slight foreign accent at times (1st gen immigrant).

So, which is right?

Ok sure if you’re prince & the revolution!

RP accent here.
Diamond 2 - Di-mond
Library 3 - Li-brer-ree.

Do you honestly call it a librar?!! The third syllable is definitely there. 🤦‍♀️

Lots of people say something close to lib-ree, me included. There is a third syllable in the middle, the ruh bit (lib-ruh-ree) but it's so faint you can hardly hear it. Diamond is a bit like this because even when it's said with three syllables, the middle one is really faint. I think it's a bit fainter in diamond.

The dia rhymes with fire.

Diremond maybe.

3 syllables isn't extra, it's correct.There is no way the vowel combination 'ia' can be one syllable.The correct pronunciation is die - er-mond.

However, I agree atherlete and assemberly are VERY annoying.

A la Marilyn Monroe

Di monds are a girls best friend

What about Shirley Bassey though.

That’s definitely more..Di ah monds are forever

It’s almost three; the a is very softly said.

I’d say library in three too.

NW England.

East Midlands and it's almost 3, the 'a' just follows the 'di' very softly and almost not there.

Depends who is speaking

If you're from the East End and you say "Diamond Geezer" its 2 syllables

If you're Queen Camilla and you say "Pass my my diamond dahlink" its obviously 4

I don’t see any difference between diamond or library. Both have 3 syllables but lots of people pronounce them as thought they have 2 or maybe 2.5 with a slightly swallowed syllable.

The middle syllable, obviously!

I think a lot depends on how fast you say the word. Said quickly diamond is obviously di-mund. But said slowly, it sounds a bit weird to say it like that I think.

Secretary is normally seh-cut-tree, but when I say Secretary of State it’s more seh-cruh-teh-ree of state. I have no idea why.

Yes but they'd said third syllable. The third syllable makes the /ee/ sound at the end. Unless you count first, third, second (which is also wrong) 🤦‍♀️😂

Sec-cut-tree is completely wrong. It's not obvious at all. Sec-re-ter-ee.

Three. Di-a-mond though the 'a' is weeny, really

I would say it as two . But if I was playing charades or explaining it to somebody else- it would probably be three die/dye a mond

As pp said - it's a diphthong, ie two vowels squished together. The English language is full of them - coal, light, crane, chive...

I'm not sure what has aggrieved me more here: missing the second syllable in library, or the miss-ordering of ordinal numbers and calling the missing middle syllable the third one. Who counts first, third, second?

Come on people.

Yes you’re right.

I meant sec ruh tree.

3

NW and I say same as you OP

NW originally
Die-mund,
Ath-leet,
Lie-br'ry,
Sec-ruh-tree

Die er mund
South East 3 Syllables
