Questions & Answers about Lubię makaron z warzywami, ale mój brat woli ryż z mięsem.

Why are the verbs lubię and woli different?

They are two different verbs, and they are also conjugated for different people.

• lubię = I like
  It comes from lubić.
• woli = he/she prefers
  It comes from woleć.

In this sentence:

• Lubię makaron... = I like pasta...
• mój brat woli... = my brother prefers...

So the endings change because the subject changes:

• ja lubię = I like
• on/ona woli = he/she prefers

Why is it mój brat and not moja brat?

Because brat is a masculine noun, and the possessive adjective must agree with it.

• mój = my, for masculine singular nouns
• moja = my, for feminine singular nouns
• moje = my, for neuter singular nouns

Examples:

• mój brat = my brother
• moja siostra = my sister
• moje dziecko = my child

So brat is masculine, which is why we use mój.

Why do makaron and not change form after the verbs?
