The function takes a string input and returns the number of characters in the input string as a lowercase English word.

[CODE]:
```python
def string_length_word(input_string):
    number_to_word = {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_strings = ["hello", "world", "python", "testing", "input", "one", "two"]
for s in input_strings:
    print(s, string_length_word(s))
```
