The name is an abbreviation for "substitute user do" (as in, do a command as if started by another user).

The sudo command is a program for Unix and Unix-like computer operating systems that allows a user to run programs with the security privileges of another user (normally the superuser, or root). The name is an abbreviation for "substitute user do" (as in, do a command as if started by another user).

Unlike the su command, users typically supply their own password to sudo rather than the root password. After authentication, and if the /etc/sudoers configuration file permits the user access, then the system will invoke the requested command.
