Questions & Answers about Muszę zejść na dół po wodę.
In Polish, the subject pronoun is often omitted because the verb ending already shows who is doing the action.
- muszę = I must / I have to
- the ending -ę tells you it is 1st person singular: I
So Ja muszę zejść na dół po wodę is possible, but ja is usually unnecessary unless you want emphasis, contrast, or clarity.
Muszę is the 1st person singular form of musieć, meaning to have to / must.
So:
- muszę = I have to / I must
- musisz = you have to
- musi = he/she/it has to
In everyday Polish, muszę often sounds like English I have to, not always as strong as formal English I must.
After musieć (to have to), Polish normally uses the infinitive of the second verb, just like English often does after have to.
- Muszę zejść = I have to go down
- Muszę iść = I have to go
- Muszę pracować = I have to work
So muszę is the conjugated verb, and zejść stays in the infinitive.
