Did you know that the first chapter is actually the zeroth chapter of the book?

Root Explanation

Zeroth is formed from "zero" (from Italian "zero", meaning nothing) and the suffix "-th" (used to form ordinal numbers). The term "zeroth" refers to the ordinal position before the first, indicating a position of nothing or absence.

Memory Tip

Think of 'zero' representing 'nothing' and the '-th' indicating an ordinal position — that's why 'zeroth' means the position before the first.
