Etymology

The word "long" traces back to Old English lang, which itself derives from Proto-Germanic langaz. This root is shared across Germanic languages (e.g., German lang, Dutch lang) and ultimately connects to the Proto-Indo-European (PIE) root dlonghos-, meaning "extended." The core idea of physical or temporal extension has remained remarkably stable over millennia, though the verb form ("to yearn") emerged later via metaphorical extension of "stretching toward" a desire.
