What is the difference between impractical and impracticable? The former is the word with which I am familiar.
The dictionary definition seems to indicate that impracticable relates to the inability to accomplish something rather than the merits of doing so. However, other grammatical references, such as Grammarist, indicate that "Impracticable is a synonym of impractical in the definition of being unfeasible or impossible to use."
Is this a matter of degrees, or is there a clear difference?
