This document discusses a study that investigated the impact of English metaphorical awareness on vocabulary retention in 60 intermediate EFL learners in Iran. The experimental group received 20 minutes of tasks involving pictorial idioms, poems, and matching for 16 sessions to increase their metaphorical awareness, while the control group received regular vocabulary exercises. The experimental group significantly outperformed the control group on tests of vocabulary retention, supporting the positive impact of metaphorical awareness training. Prior research suggests metaphorical awareness can help EFL learners better understand polysemic words and idioms by recognizing conceptual metaphors.
