Etymology
Origin of gateway
Explanation
A gateway is an opening or entrance of a gate that swings open and shut. People also use the word gateway to describe the entryway into anything, like school could be your gateway to opportunity. Study hard. Gateways are similar to doorways, with the obvious difference being the gate that you open to pass through, rather than a door. You can also use this word in a figurative way, to mean "entrance," or "means of access." For example, you could say, "That huge bank building is the gateway to the city's financial district," or "Delhi is the gateway to South Asia."
