The word "weightless" combines "weight" (from Old English wiht, meaning "a measure of heaviness") and the suffix "-less" (from Old English -lēas, meaning "without"). The suffix "-less" is commonly used to form adjectives indicating the absence of something. The term "weightless" originally described objects lacking physical weight, particularly in contexts like space travel, but it can also metaphorically describe things lacking significance.
