Learn Polish: Gdzie jest ta dobra gazeta? - Where is this good newspaper?

In Polish, adjectives change their endings to match the gender of the noun they describe. The noun here is gazeta (newspaper). Since gazeta ends in -a, it is a feminine noun. Therefore, we use the feminine form of the adjective, dobra, instead of the masculine (dobry) or neuter (dobre).

Does the word ta (this) also change depending on the noun?

Yes! Just like adjectives, pointing words like "this" must agree with the noun's gender. We use ta because gazeta is feminine. If you were pointing at a masculine noun, you would use ten, and for a neuter noun, you would use to.

The English translation says "this good newspaper". Could ta also mean "the"?

Polish doesn't have words for "the" or "a". The word ta specifically translates to "this". If you wanted to say "Where is the good newspaper?", you would usually just drop ta and say Gdzie jest dobra gazeta?. Context tells the listener you mean "the" newspaper rather than "a" newspaper.

Can I put the verb at the end and say Gdzie ta dobra gazeta jest?

You will be understood, but putting jest right after the question word Gdzie is the most natural way to ask this question in Polish. It conveniently matches the English word order of "Where is...".
