Questions & Answers about Musimy się naradzić.

Why is musimy used here, and what form is it?

Musimy is the 1st person plural present-tense form of musieć (to have to / must / need to).

So:

• muszę = I must
• musisz = you must
• musi = he/she/it must
• musimy = we must / we need to
• musicie = you all must
• muszą = they must

In this sentence, musimy tells you the subject is we, so Polish does not need a separate my (we).

Why isn’t there a word for we in the sentence?

Because in Polish, the verb ending usually already shows who the subject is.

• musimy already means we must
• so my musimy się naradzić is possible, but usually unnecessary

You would add my only for emphasis, contrast, or clarity, for example:

• My musimy się naradzić, a wy możecie już decydować.
  We need to discuss it, while you can already decide.
