'Shape' is PIE *skep- (to cut, scrape) — giving form was originally subtractive, like sculpting stone.
The external form or outline of something; to give a particular form to; to develop in a particular way.
From Old English 'gesceap' (form, created thing, creature, creation), from Proto-Germanic *ga-skapją (creation, form, shape), from *skapjaną (to create, to shape, to ordain), from PIE *skep- (to cut, to scrape). The original meaning was 'a thing created' — something that had been cut, carved, or formed from raw material. The connection to cutting reveals that the earliest concept of 'shaping' was subtractive: carving away material to reveal form, as a sculptor cuts stone. Key roots: *skapjaną (Proto-Germanic: "to create, to shape, to ordain"), *skep- (Proto-Indo-European: "to cut, to scrape").
English 'shape,' '-ship' (as in 'friendship'), and 'landscape' all come from the same Proto-Germanic root *skapjaną (to create). '-Ship' is a condition or state that has been 'shaped.' 'Landscape' is from Dutch 'landschap' — the 'shape' of the land. And German 'schaffen' (to create, to work) is a direct cognate, making shape fundamentally about creation itself.
