'''The "Wug Test" - Measuring Internalized Grammar:'''

    """
    Demonstrates Jean Berko Gleason's 'Wug Test'.
    Children are shown a novel word and asked to pluralize/conjugate it.
    If they succeed, it proves they have internalized RULES, not just imitated words.

        # Simple rule: add 'ed'

; Practical Implications
: '''Bilingualism''' → Research shows that learning two languages early improves executive function and "metalinguistic" awareness.
: '''Speech Therapy''' → Identifying delays in phonological awareness or syntax early allows for effective intervention.
: '''AI (NLP)''' → Large Language Models (LLMs) like GPT-4 attempt to simulate language acquisition through massive data, reviving debates about "Empiricism" in the digital age.
: '''Second Language Learning''' → Adult learners rely more on explicit "declarative" memory, whereas children use "procedural" memory, making child acquisition feel "effortless."
