Etymology

explain = ex<out> + plain<flat, clear>

  • ex: A Latin prefix meaning "out" or "thoroughly," often indicating removal or emphasis.
  • plain: Derived from Latin planus (flat, clear), evolving into Old French plain (clear, evident). In English, it retained the sense of clarity.

Etymology Origin:
The word "explain" originates from Latin explanare ("to make level or clear"), combining ex- (out) and planus (flat). The metaphor suggests "flattening out" complexities to reveal clarity. Over time, it shifted from literal smoothing (e.g., flattening land) to abstract clarification (e.g., making ideas understandable).
