Final answer:
In Microsoft Word, if a word does not fit at the end of a line, it is moved to the next line due to the word wrap feature.
Step-by-step explanation:
When a word does not fit at the end of a line in Microsoft Word, it is automatically moved to the next line. This is known as word wrap. The feature ensures that words are not split at the end of a line, maintaining a clean and readable text format. The action Word takes in this scenario does not depend on the syllable count of the word, nor does it automatically hyphenate the word.
