Etymology

It is late Middle English, borrowed from Old French mobilité (“changeableness, fickleness”) and directly from Latin mōbilitās, mōbilitātem, activity, speed, figuratively changeableness,[2][3][4] from mōbilis, movable, easy to move (see mobile).[2][3]

Earliest recorded meaning

Ability to move or be moved: the early 15th century in Etymonline, 1490 in the OED.[2][5]

Semantic evolution

Freedom of movement of the limbs is from 1528,[5] and changeableness, fickleness, from 1567.[5] The ability of persons to move about is from 1777,[5] and in sociology the possibility of movement between social levels from 1900.[2] A different word, mobility, the mob or common people, formed on mob after nobility in the late 17th century, is now rare.[4]
