means A strong, often sudden impulse or desire to do something; or, as a verb, to push or strongly encourage someone toward an action.

from From Latin urgēre, 'to press, push, drive,' the same root that pressures the words 'urgent' and 'urge' alike. Entering English in the 1500s, it carried that physical sense of shoving forward — and never quite lost it; an urge still feels like something pressing at your back.
