encase

The verb 'encase' is a relatively modern English formation, built from the well-established prefix 'en-' and the noun 'case'. The prefix 'en-' derives from Latin 'in-', meaning "in, into, on," which entered English via Old French and serves to transform nouns or adjectives into verbs. The root 'case' comes from Latin 'capsa', a box for holding things, related to 'capere' (to take, hold). The literal, morphemic logic of 'encase' is transparent: "to put into a case or container." Over time, its meaning expanded from the physical act of boxing something to the more general concept of surrounding or covering something completely, often for protection, as if placing it within an invisible case.

Structure: en (cause to be) + case (container) en: A prefix of Latin origin (via French), meaning "to put into," "to cause to be," or "to cover with." It functions as a verb-forming prefix. case: A word of Latin origin (from 'capsa', meaning box or receptacle). In this compound, it functions as the root noun meaning a container or covering.
