What does "laborious" mean?

The word "laborious" describes a task or process that requires a significant amount of time, effort, and energy to complete. It evokes the mental image of someone sweating over a complex project, moving slowly and methodically because the work is heavy or intricate. While "hard" can be used for almost anything, "laborious" is specifically reserved for tasks that are tedious, repetitive, or physically demanding. It is often used in professional or academic contexts to emphasize that a result was earned through sheer persistence rather than ease or quick intelligence.
