Learn Polish: Czy współtworzycie ten nowoczesny startup? - Are you co-creating this modern startup?

The prefix współ- means "co-" or "jointly" (related to wspólny, meaning "common" or "shared"). When you attach it to tworzyć (to create), it forms the verb współtworzyć (to co-create). Here, it is conjugated for the second person plural, giving us współtworzycie.

Is współ- always attached directly to the base word without a hyphen?

Yes! Unlike English where we often use a hyphen for similar prefixes (like "co-create" or "co-worker"), in Polish the prefix współ- is always fused directly to the noun, verb, or adjective as a single word. You will also see this in common words like współpraca (cooperation) and współautor (co-author).

Why doesn't the ending of ten nowoczesny startup change in this sentence?

The verb współtworzyć requires a direct object in the accusative case. Because startup is treated as a masculine inanimate noun, its accusative form is identical to its basic nominative form. That is why ten nowoczesny startup looks like it has not been declined at all.
