To repeat a process or set of steps, often with small changes each time, in order to improve something or reach a result. It is commonly used in math, computing, and design.
From Latin “iterare,” meaning “to do again, repeat,” from “iterum,” meaning “again.” The core idea of repetition stayed the same as the word moved into English. In modern use, it often suggests repeating with a purpose, not just mindless repetition.
