"Yr wythdegau"

Translation: The eighties

[japhes]

Would "dimdegau" or "serodegau" be the noughtaies

[shwmae]

Has to be said, I've never come across a term for the noughties sorry. Guess we never use one.

[shwmae]

Update: I've since come across y dimdegau once or twice for "the noughties". It's totally intuitive and would be easily understood by Welsh speakers who'd never heard it before. I like it!

[DesertGlass]

I've not seen any common use word in English either. I've heard "the noughties" but it isn't popular

[Cynphony]

In the millennium? Mileniwm?

[OwainLlyfr]

"Mileniwn", I think. (Trying hard to remember the spelling of the song title)

[shwmae]

Mileniwm is the right spelling.

[JD.Hogan-Davies]

I spent the longest century of my life yn yr wythdegau.

[Rhaidyn]

I personally prefer dwyfilau for 'two-thousands' (assuming that's how you'd represent such a thing)

[shwmae]

If you were going down that route then it’d be *dwyfiloedd as the plural of mil is miloedd. Having said that, I’ve never heard it used.
