Why this word is great
EXFORMATION — [Noun] The immense body of shared knowledge, context, and assumptions that is explicitly omitted in an act of communication, yet is its essential, unspoken foundation. From Danish eksformation, or from the English prefix ex- ("out of, from") + information, thus meaning "explicitly discarded information." Unlike "information," which is the codified data sent, or "subtext," which is a specific implicit message within a text, exformation is the entire cultural and experiential bedrock that makes sending and receiving possible. It is the unspoken history behind a knowing glance, the lifetime of botanical study that lets a scientist simply say "orchid," and the collective memory of a nation contained in the mere date "the eleventh of September." We understand each other not by what we say, but by all that we wisely, trustingly, omit.
