What does cased mean?
"Cased" functions primarily as an adjective meaning enclosed or protected within a case — a watch may be cased in gold, an instrument cased in padded wood, a mechanism sealed inside a metal housing. In engineering and manufacturing it describes components housed in protective shells, such as cased transformers or cased bearings. Separately, "cased" serves as the past tense of the verb "to case", meaning to examine or survey something carefully. This sense is strongly associated with informal American English and crime writing, where burglars are said to have "cased" a building before breaking in. The word ultimately traces back to Latin "capsa", meaning a box or container, via Old French "case". Its two strands of meaning — careful enclosure and careful observation — give it a useful double life: one literal and technical, the other idiomatic and slightly noir.
Enclosed or fitted into a protective case or casing.
"The cased telescope was carried aboard the ship without damage."
Often used attributively in technical contexts, e.g. 'cased goods', 'cased ammunition'.
Past tense of 'case': to inspect or examine a place thoroughly, especially with intent to commit a burglary there.
"The thieves had clearly cased the gallery before the theft."
Informal; strongly associated with crime reporting and detective fiction.
Burglars don't just rob a place — they 'case' it first, which is why detectives say a house was 'cased' before the heist.

Etymology of cased
The noun "case" comes from Latin "capsa" (a box), passing through Old French "case" into Middle English. The verb "to case", meaning to enclose in a case, developed naturally from the noun, while the slangy sense of inspecting premises arose in early 20th-century American criminal argot. Related words sharing the Latin root include "capsule", "casket", and "incapacitate".
