zeroth

Preceding all others

Zeroth designates the position before first in a sequence, used when counting begins at zero rather than one.

The term appears mainly in mathematics, computer science, and physics, where zero-indexing is standard: the zeroth element of an array, the zeroth law of thermodynamics.

It follows the pattern of first, second, third but backs up one step.
