an extremely pompous way of saying 'door'.
Except it's not; ingress refers to the act of passing through a door, not the door itself. A door facilitates ingress and egress; a locked door hinders it. Entrance and exit may be nouns but can equally be verbs, unlike ingress and egress. I've come across "for example" being contentious before, with or without parentheses. I've seen "perhaps" used to convey similar meaning with less ambiguity. Anyway, as Randor demonstrated, clearly solvable! :)
