Questions & Answers about Myślę, że on jest głodny i zmęczony.
Do I always need a comma before że?
Yes! In Polish, you must always put a comma before subordinating conjunctions like że (that) and bo (because). English is a bit more relaxed about commas, but Polish punctuation rules require them before these connecting words.
In English, I could just say 'I think he is hungry', dropping the word 'that'. Can I drop że in Polish?
No, you cannot drop że. While English allows you to skip 'that' in sentences like this, Polish requires the connecting word. You must always use the full structure Myślę, że... (I think that...).
Why is it just Myślę instead of Ja myślę?
In Polish, the verb ending already tells us who is doing the action. The -ę ending on Myślę means 'I think', so adding the pronoun Ja (I) isn't necessary unless you want to add special emphasis to who is doing the thinking.
Why do the words głodny and zmęczony both end in -y?
They end in -y because they are adjectives describing on (he), which is a masculine subject. If the sentence were about a woman (ona), these adjectives would take the feminine -a ending, becoming głodna i zmęczona.
