'movably' originates from English, specifically from the adjective 'movable', where the root 'move' comes from Latin 'movere' meaning 'to move' and the suffix '-able' meant 'capable of'.

'movably' developed by adding the adverbial suffix '-ly' to the adjective 'movable'. 'Move' comes from Latin 'movere', through Old French and Middle English forms such as 'moven'/'movien', and Middle English 'movable' led to modern English 'movable' and then 'movably'.

Initially it meant 'in a manner capable of being moved,' and this core meaning has been retained into modern usage.
