AH-micron, not OH-micron

This has been a public service announcement. Thank you for your time.

1. "Oh" would be Omega

O-micron is little o (aw)
O-mega is large o (oh)

[NewHendoLib]

2. Not necessarily...

From Wikipedia

In modern Greek, omicron represents the mid back rounded vowel /o̞/ , the same sound as omega.

4. Alternate pronunciation: oh-mee-kron

5. Modern Greek?

Pffft! Kids these days!

[Iggo]

12. But in modern English, it's aw-muh-krawn.

[lapucelle]

3. Aah - muh - kron

[electric_blue68]

6. Ah! Ok 👍 😉

7. I don't think you're right

It is more O than Ah. Ah is an English accent pronunciation.

9. Nope, it's the other way round

Weirdly, Oxford thinks the emphasis in British pronunciation should be on the 'mik' - which I've never heard anyone use here in Britain. But they too use 'oh' (to rhyme with 'low') as the first vowel: https://www.lexico.com/definition/omicron

For their US pronuncation, they put 'ah' first, then 'oh' - with the emphasis on 'kron': https://www.lexico.com/en/definition/omicron

Cambridge agrees with both: https://dictionary.cambridge.org/pronunciation/english/omicron

BBC radio is going with OMM-ikk-ron: https://www.bbc.co.uk/sounds/play/m00120d1 , and so is BBC TV: https://www.bbc.co.uk/iplayer/episode/m00123kq/bbc-weekend-news-evening-news-28112021

11. Citing English sources on Greek pronunciations proves my point

It’s like the British pretending the sculptures they stole are theirs to make decisions on.

14. But the point is that 'ah' is *American*, not English

The English, and indeed all the British, say 'oh' or 'omm'. I would have guessed the Greeks say 'omm', since it's the short 'o', rather than the long omega, in Ancient Greek.

If we trust Google Translate, modern Greek has dropped the final 'n', of say the first syllable as 'oh':

Whether they pronounce it the same when talking about ancient use of letters, we'd have to ask a Greek speaker.

On edit: not much difference between the start of omicron and omega now, it seems:

13. Seems so...

Checken on my digital Oxford Concise with Pronunciation. Oh-MI-cron.

10. If you're Greek, it is

oh mee krone
and the 'r' is rolled.
