What is a key feature of the holophrastic stage of language development?

The holophrastic stage of language development is characterized by the use of one-word utterances to convey entire ideas or meanings. During this stage, which typically occurs between 12 to 18 months of age, children begin to express their thoughts and needs using single words. For example, the word "milk" might be used to mean "I want milk" or "There is milk." This stage reflects the child's ability to associate a single word with a more complex idea, demonstrating emerging language skills.

The other responses illustrate stages of language development that occur later. Multi-word sentences signify a more advanced stage where children can combine words to form phrases and express more detailed thoughts. Complex grammatical structures indicate even further development, where children can manipulate language in nuanced ways. Clear articulation of sounds suggests an understanding of phonetics that typically evolves alongside grammatical development, but it is not a defining feature of the holophrastic stage. Thus, the essence of the holophrastic stage lies in the use of single words, making the correct choice one-word utterances that convey significant meaning.
