This correlates well with human language access times for nouns vs verbs. "Here, we study naturalistic speech from linguistically and culturally diverse populations from around the world. We show a robust tendency for slower speech before nouns as compared with verbs. Even though verbs may be more complex than nouns, nouns thus appear to require more planning, probably due to the new information they usually represent." https://www.pnas.org/content/115/22/5720 https://www.pnas.org/content/115/22/5720
