"The Pacific Ocean is blue."

Translation: Mae'r Môr Tawel yn las.

[tombo.wb95]

Why the 'yn' instead of just 'Mae'r Mor Tawel glas."?

[EllisVaughan]

Becuase your sentence would be "The blue pacific ocean" whereas the "yn" makes it "The pacific ocean IS blue.

Why is it "Mor Tawel" and not Cefinfor Tawel?

I don't know if you can see the "Tips & Notes" for this section on "Countries". It states: "Although Welsh has a word for ocean, 'cefnfor', all seas and oceans are named using the Welsh for sea, môr
• Y Môr Celtaidd - The Celtic/Irish Sea
• Y Môr Iwerydd - The Atlantic Ocean"

[EllisVaughan]

Whilst this may be in the notes, as a Welsh speaker I would use "cefnfor" for these names, and that is in fact the form seen in the greiriadur gomer i'r ifanc.

Thanks for the feedback. It's always good to hear from a Welsh speaker.
