What hyphen prevents two words from splitting at the end of a line?

The hyphen that prevents two Words from splitting at the end of a line is called a "non-breaking hyphen." It ensures that the two Words connected by the hyphen stay together on the same line, preventing a line break between them. This is particularly useful for phrases like "mother-in-law" or when creating compound adjectives in text formatting. In many Word processors, it can be inserted using specific keyboard shortcuts or through the character menu.
