The function takes a string input and returns the word equivalent of the length of the input string.

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

input_strings = ["hello", "world", "test", "example", "12345", "a1b2c3", "!@#$%^&*()"]
output = [string_length_word(s) for s in input_strings]
print(output)
```
