Capable of being entered; able to be accessed or gone into.
From 'enter' (from Latin 'intrare', to go within) plus the suffix '-able' (capable of being). A straightforward formation describing what can be physically or legally accessed.
Some spaces in cities are legally 'enterable' while others—even if you can physically squeeze in—are not; the word reveals how law and architecture combine to shape what humans can actually access.
