Coffee Isn't 'Copy': Korean's Missing F Sound

Korean has no sound quite like English 'f' - made by touching your top teeth to your bottom lip and pushing air through - so it's commonly replaced with a 'p'-like sound instead, turning 'coffee' into something closer to 'coppy' and 'fan' into 'pan.' This kind of substitution is a well-known transfer pattern when a target sound simply doesn't exist in the native inventory. The fix is purely physical: no lip-closing pop like 'p,' just teeth resting lightly on your lower lip with continuous airflow - no burst, just a steady hiss. Try 'fan/pan,' 'coffee/copy,' 'fine/pine.' Today, hold your top teeth gently on your bottom lip and blow air for three seconds without stopping - that's your 'f.' Then attach it to 'fan,' 'fine,' and 'coffee.' This tiny mouth adjustment instantly makes a whole category of words clearer. You've already got the muscle control - it's just a new placement!
