Questions & Answers about Ponieważ jestem słaby, to pudełko jest zbyt ciężkie, żeby je podnieść.
How does the "too... to..." structure work in this sentence?
We use the pattern zbyt + adjective + comma + żeby + infinitive. Here, it is zbyt ciężkie, żeby... podnieść. You can also use za instead of zbyt without changing the meaning (za ciężkie, żeby...).
Why is there a je before podnieść when the English translation is just "too heavy to lift"?
In English, the object is often implied in this structure, but Polish requires it to be explicitly stated. Je is the accusative neuter pronoun meaning "it" (referring to to pudełko). A literal translation of the Polish phrase would be "too heavy to lift it".
Could I start this sentence with bo instead of ponieważ?
It is generally considered poor style to start a sentence with bo. When placing the "because/since" clause at the very beginning, you should use ponieważ (or skoro). Bo is best kept for the middle of a sentence to link two clauses.
Is to acting as a linking word ("then") or just meaning "this" in to pudełko?
