The term 'ultimate objective' can be broken down into two crossword solutions: GOAL (4 letters) and ENDALL (6 letters). The word 'GOAL' is often used to describe the desired outcome of a task or project. It is usually something that is achievable and measurable. The word 'endall' is a more extreme version of the word 'GOAL'. It implies that the desired outcome is the final result, and that no further action is necessary. Together, these two words form the phrase 'ultimate objective', which suggests that the desired outcome is the ultimate end result, and that no further action is necessary.
