Etymology

user = use<to employ> + er<agent suffix>

  • use: From Old French user (to use, employ), derived from Latin uti (to use). The root implies practical application or consumption.
  • er: An agentive suffix in English, indicating "one who does" (e.g., teacher, runner).

Etymology Origin:
The word user emerged in Middle English (14th century) by combining the verb use with the agent suffix -er. It originally denoted someone who employs tools or resources, later expanding to computing and legal contexts. The logic reflects a straightforward transformation from action (use) to actor (user).
