Answer and Explanation:
The root word for residence is resid(e) and the suffix is -ence.
The root word comes from the Latin original resid(ere), meaning to reside, to dwell, to live in. The noun suffix -ence, equivalent to -ance, is used to indicate action, state, condition, or quality. It also comes from the Latin original -entia. Residence is, nowadays, used as a synonym for home, house, or habitation. We can see it originally indicated the state or the action of living somewhere.
