ashamed: [OE] Ashamed is an Old English compound, formed ultimately from the noun scamu ‘shame’. The verb derived from this, scamian, meant ‘feel shame’ as well as (as in modern English) ‘put to shame’, and in this sense the intensive prefix ā- was added to it. The resulting verb ashame died out in the 16th century, but its past participle ashamed has survived. => shame
Old English asceamed "feeling shame, filled with shame," past participle of ascamian "to feel shame," from a- intensive prefix + scamian "be ashamed, blush; cause shame" (see shame (v.)). The verb is obsolete, but the past participle lives on. Meaning "reluctant through fear of shame" is c. 1300.
