Made or produced by human effort rather than occurring naturally; artificial or synthetic, especially in a deceptive way.
From Latin 'artificiosus' (made by art), derived from 'artificium' (skillful work). The '-itious' suffix (as in 'factitious') combined with 'artifact' roots creates an adjective emphasizing artificial origin.
There's a fascinating distinction between 'artifactitious' and 'natural'—this word implies something that looks real but was intentionally constructed, which is why scientists use it to describe whether data or materials might be human-made imposters.
