The action or process of observing something or someone carefully or in order to gain information.

In science, observation is more than just seeing; it involves systematic watching, measuring, and recording of phenomena, often using instruments, to gather data objectively.

The story behind the word. The word 'observation' comes from the Latin 'observare,' meaning 'to watch, note, heed, guard.' This Latin root combines 'ob-' (meaning 'before' or 'toward') with 'servare' (meaning 'to watch' or 'to keep'). Thus, to observe is literally 'to watch before' or 'to keep an eye on' something, reflecting the careful attention required to gather information.

Word relationships

  • inspection: Inspection often implies a formal, official examination, usually for compliance or quality.
  • disregard: To ignore or pay no attention to something.
