This SANE glossary serves as a reference to name things well.

In the field of digital technologies, at the intersection of communication/marketing, research, design and industry, some terms are sometimes used in different ways, derived, reinvented.

"Historical sensibilities, cultural preferences and strategic stakes explain this relative diversity of vocabulary, to designate what, however, might well constitute a single discipline." - (Translated from french) - Stéphane Vial, Design Researcher, about "Digital Design"

"People use them often without having any idea why, what the word means, its origin, history, or what it is about. " Don Norman inventor of the term "User Experience (UX)"

For this reason, we are feeding this word database in French and English, from sources that seem safe to us. We use the terms defined by ISO as a priority, and when they exist, we also add the CCS Concepts of the Association for Computing Machinery [wiki].
