Underextension refers to the limitation of a word's application to a very narrow context or a specific object, which may not align with the conventional or intended usage of the term. For example, a child who refers to only their pet dog as "doggy" and no other dog as a "doggy" word extension is narrower than what is typically allowed. Overextension is using a word more generally or broadly than conventional meaning, which may lead to inaccurate or confusing interpretations. For instance, calling all four-legged animals dogs, a child may refer to a cow, horse, and elephant as "doggy."
