Questions & Answers about On ćwiczy codziennie i jest coraz lepszy.
Why do we use coraz lepszy instead of repeating the word for "better"?
In English, we show progressive change by repeating the comparative word (like "better and better"). Polish does this differently. You simply use the particle coraz (meaning "increasingly" or "more and more") followed by the comparative form of the adjective just once.
Is lepszy an adjective or an adverb in this sentence?
It is the masculine singular adjective meaning "better", which is the irregular comparative form of dobry (good). We use an adjective here because it describes the pronoun on (he) after the verb jest (is). If we wanted to say he practices better and better, we would use the adverb lepiej: On ćwiczy coraz lepiej.
I learned that we use the Instrumental case after the verb być (to be). Why is lepszy in the Nominative case here?
That rule applies when a noun follows the verb. If you said "He is a better player", you would use the Instrumental case for both the adjective and the noun: On jest lepszym graczem. But when an adjective stands completely alone after a form of być, it usually stays in the Nominative case.
