"English is the international language."

Translation: Τα αγγλικά είναι η διεθνής γλώσσα.

[bonbayel]

Why Τα αγγλικά is plural?

[D_..]

That's just how it is for all languages in Greek. The other option is to say 'the English language' - 'η αγγλική γλώσσα'.

It's similar in French, except they use the masculine form for the short version: le français/japonais or la langue française/japonaise etc.

Edit: You can also drop 'γλώσσα' and say 'στην αγγλική' but it is rather formal and old fashioned.

As an aside, I was listening to a podcast about Greek and the presenter said that a Greek speaker who doesn't have strong English might be heard saying "I don't speak THEM very well" referring to English - this is because of the way languages are expressed in plural!

[D_..]

Yes, same with referring to hair in plural because it is μαλλιά (neut., plural) in Greek.

[KeithMcKay3]

Hair in french is masc. pl. too - les cheveux

i believe that "τα αγγλικα ειναι η παγκοσμια γλωσσα" is correct as well because global and international tend to have the same meaning.

Thanks for the input. Added.

You could/should also (on the next tree?) change it to "mark ALL the correct answers" as is done elsewhere.
