I was in Prague in June 2016 and noticed King Charles was really popular there, featured in all sorts of monuments and tourist attractions. At one point I saw a street exhibition titled Jaký byl? with explanations about reconstructions and the like of what he was like as a person.
Much like "How's your sandwich?", which does not ask how your sandwich is feeling, but more or less about its performance in your assessment, we could possibly use the Czech question to ask about the new hire František. This is why we added How is František? as an accepted translation.
Not really. Jaký je František is a question about his character, his size, his personality, etc. What is František is more of a question asking if František is a person or a dog, if he is a doctor or a mechanic. Those would be "Co je František" or "Čím je František" respectively.
ion1122 has already answered your question. They are not the same.
Also, think of jaký, jaká, jaké (there are also plural forms) as adjectival words. So, when you ask about someone using those question words, in a way, an adjective is expected in answer. In general, anything to describe that person will be a valid response.
Things to remember:
jak is like an adverb, the answer is expected to qualify the verb (whatever the main verb in your question happens to be).
jaký is like an adjective (it has genders and plural forms), the answer is expected to qualify the person / thing that is the object of your question.
It has the same declination as all hard adjectives, for example "mladý".
singular masculine animate nominative: jaký --> accusative: jakého
singular masculine inanimate nominative: jaký --> accusative: jaký
singular feminine nominative: jaká --> accusative: jakou
singular neuter nominative: jaké --> accusative: jaké
...then there are 5 other cases as well as plural forms.
thank you, and it accord itself with the "position" of the answer, if we ask something about the subject it will be nominative and if we ask about ( I don't have the word in English but in French it's a COD) like what kind of apple do you like it'll be at the accusative right?
I added the text below to the Tips & Notes for Questions 1. (In the browser version of Duo, including on mobile devices, Tips & Notes come up when you click on the light bulb in the lesson launch pop-up.)
This exercise comes before we introduce our second case, so I avoided talking about declension.
- Jaký and který behave like hard adjectives and change forms depending on gender, so we may get jaká, jaké, která, or které.
- The remaining question words do not change with gender, but some of them will change in other ways later on in the course.
