Abstract Inferring the meaning of words and then verifying one's interpretations is widely believed to create relatively strong memories of the items. According to the available research, it is when the inferences are accurate that the learning outcomes are the most promising. The present study extends this inquiry to idioms. Fifty‐six ESL learners were presented with 21 English idioms (e.g., toe the line ) in brief contexts and they were either prompted to infer the meaning of each idiom or they were given the meaning directly. After each inferencing attempt, the correct meaning was given as feedback. This initial learning stage was followed in the same session by a meaning‐recall task where the learners were again given the correct meanings as feedback. The results of a posttest administered one week later indicate that prompting learners to make inferences is beneficial compared to directly giving the meanings on condition that the inferencing was successful.
