Etymology
The word 'sheathed' originates from the Old English noun 'scǣþ', which denoted a protective scabbard for a sword or knife. This term is of Germanic origin, related to Old Norse 'skeiðir' (sheath) and Old High German 'sceida'. The addition of the common Germanic past participle suffix '-ed' transforms the noun into a verb form meaning 'to put into a sheath' and, by extension, an adjective describing something that is encased or covered, much like a blade in its scabbard. This evolution from a concrete object to an action and a descriptive state illustrates a typical path of semantic development in English.
Analysis
sheath (from old english 'scǣþ', meaning a case or covering, specifically for a blade); ed (from old english '-ed', '-od', '-ad', a suffix forming past tense and past participles of weak verbs, and adjectives from nouns/verbs).
