The word "gateway" combines "gate," derived from Old English "geat" (an opening or passage), and "way," from Old English "weg" (a path or road). Historically, a gateway referred to a physical gate controlling access to a walled city or fortified area. Over time, it evolved metaphorically to denote any point of entry or transition, especially in technology (e.g., network gateways). The morphemes retain their original spellings, preserving the word's logical construction.
