Prosthetic & Occupy

From "Recycling Recycling" by Mark Wigley

Prosthetic (topic based):
an artificial extension that may assist or replace a missing part. It can imitate the original functions and physical conditons of the missing part. However, it may not replace social extension.

Occupy (descriptive):
to have possession of or live in (a house, etc).
to be in or fill (time or space, etc).
