תרגום - ערבית-אנגלית - ان الذي لم يعرف ...

Hi ghasemkiani,

It should be either "a foreign language" or "foreign languages"

What do you say? Is that singular or plural?

Hello, lilian canale

Thanks for the suggestion. You're right. I prefer the plural form, noting the original German quote: "Wer fremde Sprachen nicht kennt, weiß nichts von seiner eigenen." I have edited my translaton, using the plural form.
