The function takes a string input and returns a string representing the word form of the number of characters in the input.

[CODE]:
```python
def wordified_length(input_string):
    number_to_word = {
        0: "zero",
        1: "one",
        2: "two",
        3: "three",
        4: "four",
        5: "five",
        6: "six",
        7: "seven",
        8: "eight",
        9: "nine",
        10: "ten"
    }
    return number_to_word[len(input_string)]

input_string = "example"
print(wordified_length(input_string))
```

Please note that the code provided is my approximation of the function based on the tested input-output pairs. The behavior can slightly vary for inputs I haven't tested.
