lingually correct

[sanryo]

I would appreciate it if you would tell me the meaning
of the first sentence in the following excerpt.
"lingually correct" somehow reminded me of "politically
correct" and I interpreted the phrase as "Brussels,
which is sensitive to the equality among the languages."
Would you correct me and explain?
---------------
Enthusiasm for English is spreading-even in lingually correct Brussels. In China 180m students are learning English in the formal education system, and more than a fifth of Japanese five-year-olds now attend classes in English conversation. Countries as diverse as Chile and Mongolia have declared their intention to become bilingual in English over the next decade or two. And this year English was added to the curriculum studied by Mexican primary-school children, who are learning the language along with 200,000 teachers.

Welcome, sanryo.

"lingually correct" somehow reminded me of "politically correct"

That's a great association technique. Lingual(ly) as in pertaining to language, specifically speech.

Thank you very much.

You're most welcome.

I find the term 'verbal hygiene' rather sinister.

[Casiopea]

Or cunning.
