výbunými

Výbunými is a Czech adjective, the instrumental plural form of "výbušný," which translates to "explosive" in English. This grammatical form is used when describing something in relation to an explosive substance or action through the instrumental case. For example, in a sentence like "pracoval s výbunými látkami" (he worked with explosive substances), "výbunými" indicates the material being used. Similarly, it could refer to working with explosive techniques or methods.

The adjective "výbušný" itself describes properties that can cause an explosion, such as volatility, instability, or a rapid release of energy. This can apply to physical substances like gunpowder or dynamite, but also metaphorically to situations or temperaments described as explosive. In its instrumental plural form, "výbunými" is specifically used to denote the "means by which" or "in the company of" these explosive elements. It is a less commonly encountered form compared to the nominative or genitive, typically appearing in more technical or formal contexts where grammatical precision is important. The understanding of "výbunými" is therefore dependent on knowledge of both the meaning of "výbušný" and the grammatical function of the instrumental plural in Czech.
