Learn Polish: Jestem teraz zmęczony, ale będę sprzątać później. - I am tired now, but I will be cleaning later.

To talk about an ongoing action in the future, you use the future form of the verb być (to be) along with the infinitive (the dictionary form) of your main verb. In this sentence, będę means "I will be" and sprzątać means "to clean".

Does będę sprzątać mean that I will finish all the cleaning?

Not necessarily. Sprzątać is an imperfective verb, which means it focuses on the process of doing an action rather than the result. Będę sprzątać translates strictly to "I will be cleaning" or "I will spend time cleaning", but it doesn't promise that the job will be completely finished.

How do we know the speaker of this sentence is a man?

We know because of the adjective zmęczony (tired), which has the masculine -y ending. If a woman were saying this, she would change the ending to the feminine -a and say: Jestem teraz zmęczona.

Could I put teraz at the beginning of the sentence instead?

Yes! Polish word order is quite flexible. You could absolutely say Teraz jestem zmęczony or even Jestem zmęczony teraz. However, tucking the time word right after the verb, as in Jestem teraz zmęczony, sounds very natural and conversational.
