The term mobile is from the early 15c., "capacity for motion, ability to move or be moved, property of being easily movable," from Old French mobilité "changeableness, inconsistency, fickleness" and directly from Latin mobilitatem (nominative mobilitas) "activity, speed," figuratively "changeableness, fickleness, inconstancy," from mobilis "movable, easy to move."

Mobile can be described as mobile technologies and devices enabling customer and prospect mobility. Mobility describes interacting with mobile devices and the context in which those interactions occur. Frequency of usage of an app or website, web and application searches, and location services are examples of mobility. Mobile refers to mobile devices and mobility refers to how users are engaging with devices. Mobile and mobility are linked and must be thought about in concert to develop the best customer experience.
