How can multiple prefixes change the meaning of a Bulgarian verb?

In Bulgarian, as in other Slavic languages, the use of prefixes and suffixes is a primary method for deriving new words and enriching vocabulary.1

While a single prefix often alters the aspect or specific nuance of a verb, Bulgarian allows for the combination of several prefixes to modify a verb's meaning more extensively. When multiple prefixes are applied, they can serve to intensify the original action or expand its scope. For example, in the verb iz-po-raz-boleja se, the addition of multiple prefixes intensifies the meaning to describe a situation where many people fall ill.1

This process demonstrates how the language utilizes cumulative affixation to create complex semantic layers that a single prefix could not convey on its own.1
