ab initio
From the start
Ab initio is Latin for "from the beginning," used in formal and technical contexts.
In law, a contract void ab initio was never valid—not merely canceled, but treated as though it never existed.
In science and computing, ab initio methods work from first principles rather than relying on prior experimental data: ab initio calculations, ab initio molecular dynamics.
