The paper presents an analysis of Croatian agentive nominals with the suffix -ač within the Distributed Morphology approach, adopting and applying Alexiadou & Schäfer’s (2010) model. The internal morphological structure of the -ač nouns, and their eventive properties were considered in detail. The analysis has shown that the eventive/non-eventive properties of -ač nouns do not depend on animacy, but rather on the episodic vs. dispositional distinction. However, instrument nominals are distinguished from animate nominals in some respects. Croatian -ač nouns exhibit properties that cannot be completely captured by the framework adopted.
