To force something out of a position where it has been stuck or settled, often with effort.
From Old French 'deslogier,' meaning to expel from a lodge or resting place, from 'des-' (out) and 'logier' (to lodge). The physical sense of removing something from where it's lodged has remained consistent.
Medieval castles were called 'lodges'—to dislodge an army from a castle meant literally kicking them out of their dwelling, which is why the military term for removing entrenched enemies still uses this word!
