Etymology

The word "burdensome" combines "burden," derived from Old English byrthen (meaning "a load or weight"), with the suffix "-some," from Old English -sum (indicating "tending to" or "characterized by"). The suffix "-some" is commonly used to form adjectives describing qualities (e.g., "troublesome," "quarrelsome"). Over time, "burdensome" evolved to describe anything physically or metaphorically heavy or oppressive, retaining the core idea of a burdensome load.
