Here are some examples of how "diff" is used as a prefix:
* differs: To be different or unlike.
* difference: The state or quality of being different.
* differential: Relating to or involving a difference.
* differentiate: To distinguish between two or more things.
In the context of software development, "diff" often refers to a specific command or tool used to show the differences between two files or versions of a file. For example, "git diff" is a command in Git that displays changes made to files in a repository.
Therefore, "diff" essentially means "to find the differences between".
