Questions & Answers about Mama obiera ziemniaki, a ja kroję cebulę.

Why is it Mama, not moja mama?

In Polish, family words like mama, tata, babcia, and so on are very often used without a possessive like my when it is already obvious whose family member you mean.

So Mama obiera ziemniaki naturally means Mom is peeling potatoes or My mom is peeling potatoes.

Adding moja is possible, but it often sounds more emphatic or contrastive:

• Moja mama obiera ziemniaki, a twoja gotuje zupę.
  My mom is peeling potatoes, and yours is cooking soup.

Why is there a in the middle of the sentence? Does it just mean and?

A often translates as and, but it is not exactly the same as i.

In this sentence, a connects two contrasting or parallel pieces of information:

• Mama obiera ziemniaki, a ja kroję cebulę.

It feels like:

• Mom is peeling potatoes, while I am cutting the onion.
• Mom peels the potatoes, and I cut the onion.

So a is very commonly used when two subjects are doing different things:

• On czyta, a ona pisze.
  He is reading, and she is writing.

By contrast, i is more of a simple addition:

• Mama i ja gotujemy.
  Mom and I are cooking.

Why is ja included? Can Polish drop pronouns?
