Etymology

The word "old" traces back to Proto-Germanic *aldaz, meaning "grown up, adult." It is related to Dutch "oud," German "alt," and Old Norse "aldr." The Proto-Indo-European root *al- ("to grow, nourish") also gave rise to Latin "alere" (to nourish) and Greek "aldaino" (to grow). Over time, "old" shifted from emphasizing maturity to denoting age or antiquity. Its simplicity and Germanic roots make it a core, unsplittable word in English.
