or
This word primarily functions as a coordinator to present a choice or a dichotomy. It creates a mental fork in the road, signaling that the speaker is navigating between mutually exclusive options or offering a selection of alternatives. When used for clarification, it acts as an equivalence marker, bridging a technical term with a simpler one to ensure the listener understands the specific identity of the subject. In logic and computing, it shifts from a linguistic choice to a boolean operation where the presence of any single true condition satisfies the requirement.
