What word class is used with the highest frequency during the holophrastic stage?

During the holophrastic stage of language acquisition, children typically express whole ideas with single words, which often represent concrete concepts. Concrete nouns are frequently used at this stage because they relate directly to the child's immediate experiences and surroundings, such as objects, people, and familiar environments. This allows children to convey significant meaning with just one word, reflecting their understanding of the world around them.

For instance, a child might use the word "milk" to express a desire for milk, a tangible object they can see and interact with. Since children in this stage are usually focused on names of objects they encounter most, concrete nouns serve as the most frequent means of communication. This emphasis helps facilitate further language development, as children learn to associate words with their meanings in context.
