Questions & Answers about Musi pan reagować szybciej.
How do we form the comparative adverb szybciej from the basic word for fast?
It comes from the adverb szybko (fast or quickly). To make regular adverbs comparative to mean faster, you usually drop the -o ending and add -iej. Notice that the consonant changes slightly for easier pronunciation: the k in szybko turns into a c, giving us szybciej.
The English translation says 'You must', but isn't musi the he/she/it form?
Yes! When speaking formally in Polish, you use the third-person verb form (he/she/it) along with a formal title. Instead of using the informal you (musisz), the speaker literally says the gentleman must (musi pan).
Could I change the word order and say Pan musi reagować szybciej?
Absolutely. Polish word order is flexible, and Pan musi reagować szybciej is perfectly correct. Putting the verb first (Musi pan...) is just very common in Polish when giving instructions, commands, or showing urgency.
Why is the verb reagować not conjugated here?
Because it follows a modal verb. Just like in English, when you use a verb like to have to or must (musieć), the verb that comes right after it stays in its infinitive or dictionary form. Since musi is already conjugated, reagować (to react) does not change.
