Meronyms are words that denote a part of something larger. For example, "wheel" is a meronym of "car," and "finger" is a meronym of "hand." Understanding meronyms helps language learners develop a more detailed and nuanced vocabulary, as it involves recognizing how different parts relate to a whole. Teaching meronyms can improve descriptive language skills and comprehension. Activities might include breaking down complex objects into their parts or using visual aids to illustrate the relationships.
