Sense: noun/16
Side is the most versatile of these words, covering both physical location (the side of a building) and figurative dimensions (the financial side of a business). Edge refers to the sharp or narrow boundary line where a surface ends — it works for physical objects (the edge of a knife) but not for figurative aspects. Border marks a dividing line between two regions or nations and, unlike side, often implies a formal or political boundary. Margin is more specific: the blank space around a page's main text or the difference between profit and cost. Aspect and facet are figurative only: aspect focuses on a particular angle or component of a situation (every aspect of the project), while facet suggests a complex dimension of something multi-layered (a facet of her personality). Use side when the meaning is broad enough to cover both physical and figurative contexts, and choose one of the others when precision about the type of boundary or dimension is needed.

Etymology
Side traces back to Old English sīde, meaning 'flank of a person or animal' or 'long face of an object'. It comes from Proto-Germanic *sīdō, related to the adjective meaning 'wide, extending far'. Cognates include German Seite and Dutch zijde. The figurative use for 'aspect, point of view' appeared in Middle English, as did the verb sense 'to align with a party or faction'.
