locked-up

The term 'locked-up' is a phrasal verb in its participial adjective form, built from core Germanic elements. The root 'lock' originates from the Old English concept of a fastening or enclosure, evolving to signify the act of securing something with a lock. The addition of the past participle suffix '-ed' transforms the verb into a state-describing adjective. The particle 'up', a fundamental directional adverb in English, when combined with 'lock', intensifies the sense of complete and secure confinement. Thus, the literal meaning of "fastened completely" logically extended to describe both immobilized capital and incarcerated individuals, emphasizing a state of being rendered inaccessible or confined.
