Etymology: Longtime is a plain compound: "long" joined to "time," with no hidden story behind it. "Long" traces back through Old English "lang" to a Germanic root whose sense was "extended in space or time," so the word was always about length rather than duration alone. "Time" comes from Old English "tīma," which meant a fixed or appointed moment, a sense that survives in phrases like "time of day." Put together, the pair describes something whose extent in time is considerable, and the adjective use follows naturally from the noun. Nothing in its history involves a change of meaning or a notable coiner, so its interest lies in the simple logic of its two parts.
