"Náš učitel fyziky je Slovák."

Translation: Our physics teacher is Slovak.

[Hugo647250]

Is a Slovak? Or is the word in the Czech original an adjective?

[VladaFu]

A Slovak is accepted, but it is more common in English to use it as an adjective.

[Hugo647250]

So there's really no way to tell whether the word is adjective or noun.

[VladaFu]

In Czech it is absolutely clear. Slovák is a noun.

[Hugo647250]

Dekuji. I should have remembered, the adjective form is "slovensky" right?

[VimZeNevim]

"slovensky" is adverb, "slovenský" is adjective

[VladaFu]

yes

[SerhiyBila]

What't wrong with "Our teacher of physics is Slovak"?

[VladaFu]

It seems unusual https://books.google.com/ngrams/graph?content=our+physics+teacher%2C+our+teacher+of+physics&year_start=1800&year_end=2000&corpus=15&smoothing=3&share=&direct_url=t1%3B%2Cour%20physics%20teacher%3B%2Cc0 but if English natives will find it correct English it may be added in the future.

If this is still an open question, "teacher of physics" probably can safely be added as an alt. It's not as common -- not as common with "student" either -- but I don't think any harm would be done by accepting it (unlike in some other cases). https://books.google.com/ngrams/graph?content=physics+teacher%2Cteacher+of+physics%2Cphysics+student%2Cstudent+of+physics&year_start=1800&year_end=2019&corpus=26&smoothing=3&direct_url=t1%3B%2Cphysics%20teacher%3B%2Cc0%3B.t1%3B%2Cteacher%20of%20physics%3B%2Cc0%3B.t1%3B%2Cphysics%20student%3B%2Cc0%3B.t1%3B%2Cstudent%20of%20physics%3B%2Cc0#t1%3B%2Cphysics%20teacher%3B%2Cc0%3B.t1%3B%2Cteacher%20of%20physics%3B%2Cc0%3B.t1%3B%2Cphysics%20student%3B%2Cc0%3B.t1%3B%2Cstudent%20of%20physics%3B%2Cc0
