What is your favorite idiom?

@ProfessorPlum Prowess: Observable superiority in verbal , physical, moral, or other qualified trait under scruitiny.

@SteelHands I would have summed it n one word: Skillfulness.

@ProfessorPlum Skill is practiced agility, accuracy and coordination of person to carry out mental and physical tasks.

Prowess is the immensity of the creative thought to rise to a challenge.

You shouldn't let the distinction confuse you since by today's literary guides our historical language is apparently 'too wordy' for them to bother to learn properly. So is also beyond their intellectual depth to teach anyone.

I did warn you not to keep nit picking. Maybe you should consider reading some old books. There are plenty of contextual comparisons you could make to throw off that horrible education you were duped by.
