A common language is a necessary prerequisite for effective communication. Considering the fact that most specialised knowledge has been documented and published on natural languages, proper terminology is a necessary prerequisite for the effective transfer of knowledge. Roche (2012) writes that “terminology as a scientific discipline is crucial if we consider that its primary aim is to understand the world, describe the objects that populate it and find the right words to talk about them”. As such, terminology plays a major role in ensuring legal certainty. There is no doubt that terminology databases are the best places to store detailed descriptions of legal terminology.
