Questions & Answers about Mój narzeczony jest młodym uczonym.
Are narzeczony and uczony nouns or adjectives?
They are both substantivized adjectives! This means they function as nouns in the sentence but decline exactly like regular adjectives. Narzeczony (fiancé) is in the nominative case as the subject. Uczony (scholar) is in the instrumental case (uczonym) because it follows the verb jest.
Why do both młodym and uczonym have the exact same -ym ending?
When you state a person's profession or identity using jest (is), you must use the instrumental case. Because uczony declines like an adjective, its masculine instrumental form is uczonym. The word młody (young) is a regular adjective describing it, so it also takes the instrumental ending. Since both follow adjective declension rules, they both get the -ym ending.
How would this sentence look if it were about a female fiancée?
Because these words decline like adjectives, you simply use the feminine adjective endings! Mój narzeczony becomes Moja narzeczona. For the instrumental part after jest, młodym uczonym becomes młodą uczoną. The final sentence would be: Moja narzeczona jest młodą uczoną.
Why does a word for scholar (uczony) look so much like the verb to learn (uczyć się)?
