Etymology

Origin of mobilize

First recorded in 1830–40; back formation from mobilization; mobile, -ization

Explanation

Use the verb mobilize to describe preparing something — or someone — to spring into action, or to be put into use. You might mobilize the troops, or even your classmates, into action. A busy mother might mobilize her kids to grab their lunches and head out to the bus stop on time, and a detective might mobilize her resources before tracking down a wily criminal. Mobilize literally means "make mobile," and the Latin root is mobilis, "movable, pliable, or flexible."
