The act of exercising, practicing, or training, especially in religious, intellectual, or spiritual disciplines.
From Latin exercitatio, formed from exercitare (to exercise frequently) plus -tion suffix. This is a learned, formal noun rarely used in everyday speech.
Academic writers in the 16th and 17th centuries loved 'exercitation' to describe scholarly practice and mental discipline—you'll find it in old philosophy texts describing rigorous thinking as 'exercitation of the mind.'
