legendę
"Legendę" is the accusative singular form of "legenda," meaning "legend" or "story" in English.
Here, 'legendę' is in the accusative case, indicating the direct object of the verb 'cytuję' (I quote).
Cytuję legendę, która opowiada o smoku wawelskim.
I am quoting the legend that tells the story of the Wawel dragon.
In this sentence, 'legendę' is again in accusative case and represents the direct object of the verb 'znajdziesz' (you will find).
W książce znajdziesz legendę o królu Arturze.
In the book, you will find a legend about King Arthur.
This usage of 'legendę' identifies it as the focus of the verb 'przedstawiamy' (we are presenting) in the accusative case.
