ambulatory

Etymology

The noun is borrowed from Medieval Latin ambulātōrium (“a place for walking, a covered walk”),^[2][3][4][5] recorded in British sources from the 13th century,^[2] the neuter of Latin ambulātōrius used as a noun.^[5][6] The adjective is partly borrowed from Middle French ambulatoire (“moving from place to place; changeable”) and partly borrowed from Latin ambulātōrius (“movable; suited for walking”),^[2][3] from ambulātor (“a walker”),^[3] formed on the past participle stem of ambulō (“to walk, go about”),^[2][3][7][5] the source of amble.^[3][5] Its medical senses follow German ambulatorisch.^[2]

Earliest recorded meaning

As a noun, a place for walking, such as a covered walk: 1483–4, in the churchwardens' accounts of Ashburton.^[2] Merriam-Webster dates the noun to about 1616, and the Shorter Oxford to the mid 16th century.^[5][6] As an adjective, moving from place to place: 1604, in Dallington's View of Fraunce;^[2] Etymonline dates the adjective to the 1620s and Merriam-Webster to 1622.^[3][5]

Semantic evolution

The noun came to be used especially of the aisle running behind the high altar and round the apse of a church,^[2][5][8] and of the gallery of a cloister.^[5][8] The French adjective was first used of a parliament that moved from place to place, and the first English use follows it.^[2] In French law a person's will was said to be ambulatoire, free to be changed until death,^[2] and the English sense "not fixed, alterable" is recorded from 1625,^[2] surviving in law of a will that can be revoked.^[5][8] The senses "of walking" and "able to walk" (1625, 1648) have no French parallel until later.^[2] Johnson (1755) defined it as having the power of walking, quoting Wilkins's Mathematicall Magick.^[9] In medicine it once described a disease that spread through the body (1684–1921);^[2] from 1819, after German, it was used of treatment of outpatients, and since 1864 of an illness that does not keep a person in bed.^[2]
