O.E. scapan, pp. of scieppan "to create, form, destine," from P.Gmc. *skapjanan "create, ordain" (cf. O.N. skapa, Dan. skabe, O.Fris. skeppa, O.H.G. scaffan, Ger. schaffen), from PIE base *(s)kep- "to cut, to scrape, to hack" (see shave), which acquired broad technical senses
and in Gmc. a specific sense of "to create." O.E. scieppan survived into M.E. as shippen, but shape emerged as a regular verb (with pt. shaped) by 1500s. The old past participle form shapen survives in misshapen. Phrase Shape up (v.) is attested from 1865 as "progress;" from 1938 as "reform;" shape up or ship out is attested from 1956, originally U.S. military slang, with the sense being "do right or get shipped up to active duty."
