Definitely not intelligent...
Acquiring languages is... exposure, mostly.
I am a native of Brussels, Belgium, two official languages there (French, Dutch).
Then came English and German in school, pop music or TV/movies.

I had to survive 25 years of career as pilot in USA.
After that airline bankruptcy, went to fly in Argentina (learned Spanish).
Just retired to the beach in Brazil (improving my Portuguese).

Languages were a tremendous help in my career.
Every kid (besides English) should learn 1 or 2 languages.
