Semantic gender norms are presented for 24,037 Dutch words. Eighty participants rated 6,017 words each on a 5-point Likert scale ranging from feminine to masculine. Each word was rated by 10 male and 10 female participants. The collected norms show high reliability and correlate well with similar norms in English. We show that semantic gender is distinct from other lexical dimensions such as valence, arousal, dominance, concreteness, and age of acquisition. Semantic gender is not the same as the grammatical gender of words, either. The collected norms can be predicted accurately using a semantic space based on word association data. A dimension explaining a good amount of variance is present in this space, indicating that semantic gender is an important component of the human meaning system.
