Our knowledge of how to speak is

• A. Explicitly learned
• B. Explicitly codified
• C. Implicit and not easily explained how we do it
• D. Only taught in schools

Answer: (C)

Our knowledge of how to speak is largely implicit—the rules and patterns we use come from exposure and practice, not from a set of clearly stated instructions. We acquire pronunciation, word usage, and the intuitive sense of what sounds right through listening and speaking with others, often without being able to articulate the exact rules behind it. Much of grammar feels automatic; we can produce and understand sentences we couldn’t neatly spell out in terms of formal rules.

Explicit instruction can help by teaching vocabulary or specific grammar points, but it doesn’t explain how fluent speech is actually produced or understood in real-time. Language is learned and refined primarily through social use and immersion, not through schooling alone.
