reagujcymi

Reagujcymi is a nonstandard form that would correspond to a Polish present active participle meaning “reacting” or “responsive.” In proper Polish orthography the instrumental plural of the participle is reagującymi. The base verb is reagować (to react, to respond), and its present active participle is reagujący, with the instrumental plural ending forming reagującymi.

In Polish grammar, present active participles like reagujący and its variations function as adjectives or adjective-like modifiers. They describe agents who perform the action of the verb in the present. The participle agrees with the noun it modifies in gender, number, and case. The instrumental plural form reagującymi is used when the modified noun is in the instrumentally case plural, or when the phrase stands in certain syntactic constructions that require that form.

Usage notes and examples:

- Osoby reagujące na bodźce często wykazują różne reakcje fizjologiczne. (People reacting to stimuli often show various physiological responses.)

- W naukach o zachowaniu opisuje się grupy reagujące na określone bodźce w eksperymentach. In such contexts, the standard form reagującymi appears in constructions like “z osobami reagującymi na bodźce.”

Summary:

Reagujcymi is not the standard spelling for this grammatical form. The correct instrumental plural form is reagującymi, the broader paradigm being part of the present active participle reagujący/reagująca/reagujące and their declined variants. This form is used to describe agents that react, typically in formal or scientific Polish.
