Uczestnikami

Uczestnikami is the instrumental plural form of the Polish noun uczestnik, which means a person who takes part in an event, activity, or process. The word is formed from the verb uczestniczyć (to participate) with the agent-noun suffix -nik, indicating a person associated with participation.

In Polish, uczestnik is masculine personal. Its basic case forms include: plural nominative uczestnicy, genitive uczestników, dative uczestnikom, and accusative typically the same as genitive for masculine animate nouns. The instrumental plural form is uczestnikami and is used in contexts where the instrumental case is required, most notably after the preposition z (with), as in z uczestnikami meaning with the participants. It can also appear as a predicative complement after the verb być in certain constructions, for example: Najważniejszymi uczestnikami konferencji byli profesorowie (The most important participants of the conference were the professors).

Common collocations include uczestnik konferencji (participant of a conference), liczba uczestników (number of participants), and grupa uczestników (group of participants). The term is widely used in formal, academic, and event-related language to refer to people who take part in a given activity or event.

Etymology: the noun is derived from the verb uczestniczyć via the agent-noun suffix -nik, reinforcing its meaning as a person who participates in something.
