What does the word easier said than done mean?

The phrase "easier said than done” is used to express that something may sound simple or straightforward to accomplish but is actually more challenging or difficult in practice. It implies that there is a significant difference between the conception and execution of a task or action.

For example, one might make a statement like, "It's easier said than done to climb Mount Everest." While it may seem like an achievable goal in theory, the actual process of climbing the world's highest mountain is incredibly demanding, requiring immense physical preparation, mental fortitude, and the management of various risks and challenges.

The phrase underscores the gap between theory and practice, reminding us that what appears simple on the surface may require substantial effort, planning, and resources to achieve in reality. It also highlights the importance of considering practical factors and potential obstacles when embarking on a task, rather than relying solely on theoretical assumptions or idealistic expectations.
