Tariq Looks more like post-editing of machine translation that either did not happen or was rushed through. Or a typo that was flagged by the spellchecker and then not properly corrected.

Leif this is a long shot, but is it plausible that this was some kind of irony?
Using incorrect grammar I mean

Leif Ohman Jul 30, 2020:

Why "kunskap av" rather than "kunskaper i"? Normally, people who are proficient in a language have "kunskaper i" the language in question.
Notice the plural form. The choice of "av" seems odd, but the singular form of "kunskap" suggests very strongly that the sentence was not constructed by a native speaker.

@ Chris and all Hello

the thing is, if this is for a language company like Berlitz, I think the mentioning of (foreign) language would be an absolute must for them.
So working from what you suggested, maybe,

"Broaden your horizons. Add another language to your repertoire"?

What do you think?
