UK: dɪsˈsɜːvɪs | US: dɪsˈsɜːrvɪs

Definition
  1. n. an action or behavior that harms or fails to help someone or something

Structure
dis <opposite of>service <assistance>
Etymology

The word "disservice" combines the prefix "dis-" (from Latin, meaning "opposite of" or "lack of") with the root "service" (from Old French "servise," meaning "assistance" or "help"). The prefix "dis-" negates the positive connotation of "service," creating a term that describes an action contrary to helpfulness—often implying harm or neglect. This logical pairing reflects the word’s evolution in Middle English to denote a harmful or unhelpful act.

Examples
  1. Spreading false rumors about a colleague is a great disservice to teamwork.

  2. The biased article did a disservice to the scientific community.

  3. Ignoring customer complaints is a disservice to your business.

  4. He felt the review was a disservice to his hard work.

  5. Cutting funding to education does a disservice to future generations.
