14. (15 points) In the four idioms “虚有其表”, “表里如一”, “一见如故”, “故弄玄虚”, each Chinese character represents one of 11 consecutive non-zero natural numbers. The same character represents the same number, and different characters represent different numbers. Additionally, “表” > “一” > “故” > “如” > “虚”, and the sum of the numbers represented by the four characters in each idiom is 21. What is the largest number that “弄” can represent?
【Analysis】There are clear size relationships in "表, 一, 故, 如, 虚", in fact, they are all numbers with repeated digits in idioms, the sum of each four-character idiom is 21, so the total sum is $21 \times 4=84$. All numbers are 11 consecutive non-zero natural numbers, so their sum must be a multiple of 11. They could be: (1) $1--11$, the sum is 66, the sum of the 5 repeated digits is $84-66=18$; (2) $2--12$, the sum is 77, the sum of the 5 repeated digits is $84-77=7$. Since each number is different, this situation is impossible. Therefore, the sum of the five repeated digits is 18, and all numbers are $1--11$. The repeated digits can only be the following possibilities: (1) $1, 2, 3, 4, 8$; (2) $1, 2, 3, 5, 7$; (3) $1, 2, 4, 5, 6$. Substituting, we find that only situation (3) fits. After filling in each number, we get 虚 $=1$, 故 $=4$, 弄 and 玄 can only be $9, 7$, thus solving the problem.

【Solution】According to the analysis, the sum of the five repeated digits in "表, 一, 故, 如, 虚" is 18. Since all numbers are $1--11$, the repeated digits can only be the following possibilities: (1) $1, 2, 3, 4, 8$; (2) $1, 2, 3, 5, 7$; (3) $1, 2, 4, 5, 6$.

Substituting, we find that only situation (3) fits. After filling in each number, we get 虚 $=1$, 故 $=4$, 弄 and 玄 can only be $9, 7$, so the maximum value of 弄 is 9.

Answer: The largest number that “弄” can represent is 9.
