Questions & Answers about Myślę, że twoje pomysły są ciekawe.
Why do we use twoje instead of twój or twoi here?
Twój is singular. Since we are talking about multiple ideas, we need a plural form. In Polish, plurals are split into masculine personal (groups with at least one man) and non-masculine personal (everything else, including objects). Because pomysły (ideas) are objects, we use the non-masculine personal possessive pronoun twoje. If we were talking about male people, we would use twoi.
Is the comma before że always required?
Yes! Unlike in English, Polish punctuation rules strictly require a comma before the word że (that) whenever it introduces a new part of a sentence. You will see this same comma rule with other joining words like bo (because) and ale (but).
How do we know to use the -y ending for the plural pomysły?
The singular word is pomysł (idea), which is a masculine noun for an inanimate object. It ends in a hard consonant (the letter ł). For these types of nouns, the standard plural ending in the Nominative case is -y.
