Best practice

Common error
Avoid using the phrase "strenuous task" as a generic descriptor. Without specific details, it can sound vague and uninformative. Always provide context to illustrate why the task is considered strenuous and what challenges it presents.

Is it redundant to say "very strenuous task"?
While not grammatically incorrect, "very strenuous task" can be redundant. "Strenuous" already implies a high degree of effort, so using intensifiers like "very" may not add significant meaning. Consider using a more descriptive adjective or elaborating on the task's challenges instead.
What makes "strenuous task" different from "difficult task"?
