The function takes an input string and returns the length of the string as a word.
[CODE]:
```python
def length_as_word(s):
    number_words = {1: "one", 2: "two", 3: "three", 4: "four", 5: "five", 6: "six", 7: "seven", 8: "eight", 9: "nine", 10: "ten"}
    return number_words[len(s)]

# Example usage:
input_string = "example"
output = length_as_word(input_string)
print(output)  # seven
```
