The Dictionary of Invisible Meanings takes shape from the observation that one of the most important barriers to cross-disciplinary collaboration is the different use of language between disciplines. The same terms take on very different meanings across different disciplines, often in contrast with their more commonplace, colloquial usage. This thread of the work of the Network aims to bring to the fore some of the multi-layered meanings that words often hide: words that are transparent signifiers to those who are educated in a specific discipline become (wittingly or unwittingly) opaque barriers to understanding by and communication with those outside the field.
