non-ambulatory

The word is a modern English formation built upon the classical Latin root ambulare, meaning "to walk," which itself is traced back to the Proto-Indo-European root h₂el-, "to wander, go." The Latin verb gave rise to ambulatorius, "pertaining to walking," which entered English as "ambulatory." The prefix non-, directly from Latin non meaning "not," is systematically attached to create a negation. Thus, the literal construction "not pertaining to walking" evolved into the specific medical and formal term describing a person who is unable to walk or a condition that does not involve walking.
