Word of the day: Onerous

Some words enter public discussion not because they are new, but because they describe familiar situations with unusual precision. The word is particularly useful when describing responsibilities, duties, or conditions that feel difficult to carry or fulfil. While people often speak of tasks being hard or demanding, “onerous” conveys a stronger sense of burden. It suggests something that requires considerable effort, causes strain, or places heavy demands on a person, organisation, or system.Onerous describes something difficult, burdensome, or demanding to carry out. It is commonly used for responsibilities, obligations, rules, or tasks that require significant effort and may feel troublesome or exhausting.The word onerous comes from the Latin term onerosus, meaning “burdensome” or “loaded”. It is derived from onus, meaning “burden” or “load”. The term entered English during the sixteenth century and was initially used in legal and administrative contexts to describe obligations that imposed significant demands or hardship. Over time, its use expanded beyond formal settings and became associated with any task, responsibility, or condition that feels particularly difficult to bear. The original idea of carrying a heavy load remains central to the word's meaning today.
