"Baby talk" is a term used to label the word forms that many adults use when speaking to c

hildren. Examples in English are choo-choo for "train" and bow-wow for "dog". Baby talk seems to exist in every language and culture. At least two things seem to be universal about baby talk: the words that have baby talk forms fall into certain semantic categories(for example, food and animals)and the words are " phonetically simpler" than the adult forms(for example, tummy[t∧mi]for "stomach"[st∧m？k]). List all the baby talk words you can think of in Chinese; then(1)separate them into semantic categories, and(2)try to state general rules for the kinds of phonological simplifications that occur.
