Verbs and nouns vary in many ways-including in how they are used in language and in the timing of their early learning. We compare the distribution of semantic features that comprise early acquired verb and noun meanings and measure their effect on learning. First, couched in prior literature, we use semantic feature data to establish that features pattern on a hierarchy of complexity, with perceptual features being less complex than other features like encyclopaedic features. Second, given overall semantic and syntactic differences between nouns and verbs, we hypothesize that the preference for directly perceptible features observed for nouns will be attenuated for verbs. Building on prior work using semantic features and semantic networks in nouns, we find that compared to early learned nouns (
