Questions & Answers about Moja siostra gra na skrzypcach, a mój brat na flecie.

Why is it moja siostra but mój brat?

Because Polish adjectives and possessives must agree with the noun in gender, number, and case.

• siostra is feminine, so you use moja = my
• brat is masculine, so you use mój = my

So:

• moja siostra = my sister
• mój brat = my brother

This is very normal in Polish, unlike English, where my never changes.

Why do we say gra na skrzypcach and na flecie?

Because in Polish, when you say that someone plays a musical instrument, you usually use:

grać na + instrument

So:

• grać na flecie = to play the flute
• grać na gitarze = to play the guitar
• grać na pianinie = to play the piano
• grać na skrzypcach = to play the violin

This is just the standard Polish pattern. English uses a direct object (play the violin), but Polish normally uses na with the instrument.
