Questions & Answers about Můj dědeček nejraději sedí doma a čte noviny.
Because můj has to agree with dědeček (grandfather) in gender, number, and case.
- dědeček is masculine animate, singular, nominative
- so the possessive adjective is můj
Compare:
- můj dědeček = my grandfather
- moje babička = my grandmother
- moje auto = my car
- mého dědečka = my grandfather (in a different case, for example accusative or genitive in some contexts)
So here můj is correct because dědeček is the subject of the sentence.
Yes. Dědeček is a more affectionate or softer form of děda.
Very roughly:
- děda = grandpa
- dědeček = grandpa / grandad / dear grandpa
Both mean grandfather, but dědeček often sounds warmer, more affectionate, or more family-oriented. Learners will often see Czech using diminutive forms like this.
