Etymology
The word 'unrolled' is built upon the core verb 'roll,' which traces its lineage to the Latin rota, meaning "wheel," via the diminutive rotulus, "a little wheel." This concept of circular motion evolved into the action of forming a cylindrical shape. The Germanic prefix un- is attached to indicate the reversal of this action, a productive pattern in English for creating opposites. The suffix -ed follows the standard Germanic convention for marking the past tense. Thus, the literal morphemic logic of "reversing the state of having been rolled" seamlessly translates into the modern meaning of opening or spreading out something that was previously coiled or wound.
