orovými
orovými is a Czech word, specifically a masculine instrumental plural form of the adjective "orový," which translates to "oat" or "oaten" in English. Therefore, "orovými" refers to things that are made of or related to oats, but in a way that requires the instrumental case. The instrumental case in Czech is used to indicate the instrument or means by which an action is performed, or to describe the company or association with something.
For example, one might say "krmit koně orovými otrubami," meaning "to feed the horse with oat bran."
