This would imply that a group of subjects is performing an action. The root of the word would determine the specific meaning. If it were related to the verb "vyívat," it might mean something like "they are yawning." If it were derived from another verb, the meaning would change accordingly. To understand the precise meaning of "vyivují," it would be necessary to know the verb it originates from and the context in which it is used. Its grammatical function is most likely that of a present tense verb describing an action being done by multiple entities.
