Challenge 192: Christmas Communications

Can you find a language that is spoken by three or more elves?

There are nine elves on Santa’s committee organising distribution of presents. The elves are from all over the world, but none of them speak more than three languages. However, Santa has chosen them carefully so that if you pick any group of three elves, at least two of them will have a language in common.

Is there a language that is spoken by three or more of the elves?

Explain your reasoning carefully!
