Word: Unreal

In Lacan's chapter on The Subject and the Other: Alienation, he talks about the unreal in response to the embodiment of a missing organ: the labido.
According to dictionary.com, unreal is defined as:

"1.not real or actual.
2.imaginary; fanciful; illusory; delusory; fantastic.
3.lacking in truth; not genuine; false; artificial: unreal propaganda serving as news."

However, Lacan says "Unreal is not imaginary. The unreal is defined by articulating itself in a real way that eludes us, and it is preciesly this that requires that it's representation should be mythical[...]" 205. This idea of the unreal ultimately relates back to his discussion of the Other, which also is a creature of the unreal yet tries to embody itself against the subject.
