“Gate” you will know. A gate can be made of wood or metal (verja), and there are gates (barreras) in fields. If you have flown recently, you may have heard “please go to gate 8 (la puerta 8) to board your flight.
There is also a verb form – to gate crash (colarse). If a mortal “gatecrashes” an event or party he enters it without permission or an invitation. This is unacceptable behaviour. Such a mortal becomes a “gatecrasher” (colado).
So, have you ever gatecrashed an event?
