This document discusses how children learn abstract concepts and terms. It explains that children begin by learning concrete words for physical objects and actions, and then progress to more complex abstract ideas. Abstract terms like "love" and "freedom" are difficult for children to understand fully because their meanings can change depending on experience. The document also describes how children might learn the meanings of feeling words like "hungry" and "hurt" by associating the words with situations and their own feelings. Children test hypotheses about word meanings and expand their understanding of words over time through multiple examples of usage.
