The Role of Depth versus Breadth of Vocabulary Knowledge in Success and Ease in L2 Lexical Inferencing

This study determines whether breadth and depth of vocabulary knowledge are related to L2 ease and success in lexical inferencing. To this end, two tests measuring vocabulary breadth and depth were administered to 50 participants. Two weeks later, all participants received an inferencing task and rated the degree of perceived ease in inferencing on a 6-point Likert-scale questionnaire. The findings indicated that although both vocabulary breadth and depth played an important role in lexical inferencing success, vocabulary breadth made a more important contribution. The results further revealed that neither vocabulary breadth nor depth had a significant effect on perceived ease of inferencing.
