    "abstract": "In English, many words can be used flexibly to label artifacts,\nas nouns, or functional uses of those artifacts, as verbs:\nWe can shovel snow with a shovel and comb our hair with a\ncomb. Here, we examine whether young children form generalizations\nabout flexibility from early in life and use such\ngeneralizations to predict new word meanings. When children\nlearn a new word for an artifact, do they also expect it\nto label its functional use, and vice versa? In Experiment 1,\nwe show that when four- and five-year-olds are taught a first\nnovel word to label a familiar action—e.g., that bucking means\nshoveling—they exclude the artifact involved in this action—\ni.e., the shovel—as the meaning of a second novel word (e.g.,\ngork). This suggests that children spontaneously expected the\nfirst novel word—which referred to the action—to also refer to\nthe artifact. In Experiment 2, we show that this pattern extends\nto words that label novel actions involving novel artifacts, suggesting\nthat children expect any word for an action to label the\nartifact that helps carry out that action. Experiment 3 traces\nhow such generalizations may arise in development. In particular,\nwe show that while four- and five-year-olds each expect\nwords to label artifacts and their functional uses, three-yearolds\nmay not.",
