How do you pronounce Dahlia?

[ShutUpAlex]

Family are feuding

Daaah-lia yanbu
Day-lia yabu

Daar-lee-ah

I'm British, and very unamerican

Duh lie lu

Just realised I thought it was Delilah

It really depends. The flower is a day-lee-ah. The famous murder victim is the Black Dah-lee-ah.

I'm Scottish -only ever heard people say Dah-lia. Day-lia sounds incredibly English to me. But when people say "UK" or "British" that's usually what they actually mean anyway.

When MIL (English) visits, and we talk about the garden she would always say "Day-lia" which sounds incredibly wrong to my ears.

I'm Scottish and it's definitely day-lee-ah.

Day-lia

I've always said Day-lee-uh but read the Wikipedia entry posted earlier. It seems that the flower is named after a Swedish naturalist called Dahl. Presumably he pronounced his name in the same way as Roald Dahl who had a Norwegian backtound. That meant that I've been saying it wrong all my life and it should be Dar-lia.

Not really- regardless of the spelling and origin, I'm pretty sure the standard UK English pronunciation is daylia. It's pretty normal to have local pronunciations of foreign imported words.

Here is the Cambridge Dictionary page for it. The UK pronunciation is day-lia, the US is dah-lia (both sound files included on the page).

As @DoTheNextRightThing mentioned, I imagine some people here may have heard it pronounced in media as dah-lia due to the Black Dahlia, the US murder case that has been in several movies now.
