Step-by-step explanation:
An example of linguistic overextension that a 2-year-old might make is A) Calling all animals "doggie". This occurs when a child applies a word they have learned to a wider set of objects or situations than is appropriate.
The concept of overextension is a part of language acquisition in young children, where they attempt to apply rules and words they know to new scenarios.
This is different from language-specific details like grammar or pronunciation, and more about the conceptual assignment of words to objects or categories.
For example, a child might learn the word 'doggie' and then use that word to refer to all four-legged animals, including cats, cows, and horses.
By doing so, the child is overextending the word 'doggie', which should be specifically used for dogs, to other animals. This is a normal part of language development and illustrates that while the child is absorbing the rules of language, they are still learning to apply them correctly to the world around them. The correct option is A) Calling all animals "doggie"
