Root Explanation

Lossless → It is formed from "loss" (from Old English *los*, meaning the act of losing or being deprived of something) and "-less" (meaning without). The word "lossless" describes a state of being without loss, particularly in contexts like data compression where no information is lost.

Memory Tip

Think of 'loss' meaning to be deprived of something, and '-less' meaning without. So, lossless means without any loss.
