Dereferenceable
To dereference is to access a value or object located in a memory location stored in a pointer—the pointer directs you to the stored value. In the context of Linked Data (LD), dereferencing is used in relation to Uniform Resource Identifiers (URIs) and whether or not they are dereferenceable. A dereferenceable URI is one that resolves to a webpage: it can turn from an abstract reference into something more concrete, namely a web resource. If you can put a URI into the address bar of a browser and access a webpage through that address, then it is dereferenceable.
