Related to the system of prisons and rehabilitation aimed at correcting criminal behavior, or serving to correct or fix something.
From 'correction,' from Latin 'corrigere' (to make straight), combining 'cor-' (together) and 'regere' (to guide). The sense is of guiding or straightening out behavior.
The name 'correctional facility' is actually quite optimistic—it assumes prisons can 'correct' behavior and straighten people out, though historians argue this philosophy only became dominant in the 1800s; before that, prisons were just places to hold people, not fix them.
