The antonym for the term "more immotile" is more mobile. When we talk about immotility, it refers to the inability to move, whereas mobility means the ability to move or be moved freely. Therefore, if something is more immotile, it cannot move, and if it is more mobile, it can move efficiently. The term more immotile is commonly used in scientific or medical contexts, usually referring to cells or microorganisms that are unable to move. Conversely, more mobile is often associated with the movement of animals, machines or any other living being that can travel from one place to another.
