This is the 3310th most frequent Polish word.
twoją
"Twoją" means "your" (feminine singular accusative form) in English.
In this sentence, 'twoją' is used as a possessive adjective referring to a feminine noun ('książkę', which means 'book') in the accusative case.
Widzę twoją książkę na stole.
I see your book on the table.
Here, 'twoją' is used in a dative construction implying praise or liking; however, the discrepancy lies in the English translation fitting more contentedly into convention.
Podoba mi się twoja nowa sukienka.
I like your new dress.
In this case, 'twoją' applies to instrumental reasoning for factual consensus compounded in English martial.
