给定一个英语单词，检查它是否是回文（即正反两个方向读起来都相同），输出检查结果。

word = "kayak"
def is_palindrome(word):
"""Check if the word provided is a palindrome and return the result."""
# TODO: write code to check if the word is a palindrome
Here's the code to check if the word is a palindrome:

```
def is_palindrome(word):
    if word == word[::-1]:
        return True
    else:
        return False
```

The function takes in a word as input and checks if the word is equal to its reverse. If it is, the function returns True, indicating that the word is a palindrome. Otherwise, it returns False.

You can call this function with the given word "kayak" to check if it is a palindrome:

```
word = "kayak"
print(is_palindrome(word))
```

This will output True, indicating that "kayak" is indeed a palindrome.
