Learn Polish: Ta umowa jest pilna. Niech dyrektor ją podpisze. - This contract is urgent. Let the director sign it.

The word niech translates to "let" or expresses a strong suggestion like "should". To give a command to a third party (like he, she, they, or a specific person like the director), you simply use niech followed by the subject and the regular third-person verb. So niech dyrektor... podpisze means "let the director sign".

Wait, isn't podpisze the future tense? Can we use future tense with niech?

Yes! The verb podpisać (to sign) is a perfective verb, meaning it focuses on the completion of an action. For perfective verbs, their regular conjugated forms naturally act as the future tense. When using niech to say "let him do [a completed action]", you use this exact form.

Why is the pronoun ją used here to mean "it"?

In Polish, pronouns must match the grammatical gender of the noun they replace. The word for contract is umowa, which is a feminine noun. Because the contract is the direct object receiving the action (it is being signed), it takes the accusative case. The feminine accusative form for "it" or "her" is ją.

Why does ją come before the verb podpisze instead of after it?

Short object pronouns like ją generally avoid being the very last word in a sentence if possible. Putting the pronoun before the verb (Niech dyrektor ją podpisze) sounds much more natural and flows better for a Polish speaker than leaving it at the very end.
