Every adult native speaker of Russian knows that kon’ is masculine and lan’ is feminine, although 3 ^rd declension nouns present some difficulties in the first and second language acquisition. However, will the fact that these nouns are less frequent than masculine nouns ending in a consonant or feminine nouns ending in -a/ja play a role for online subject-predicate agreement processing? Or will subject-predicate agreement processing be more problematic with subjects of a certain gender? Finally, some final consonants are more characteristic for feminine gender, while the others for masculine gender. Are speakers sensitive to this? We present two experiments addressing these questions. We found that all three factors play a role, but for different tasks (online agreement processing or determining the gender of a novel word) and at different processing stages.
