Level design is a critical aspect of game development, as it provides a common language for game developers to use when designing game levels, improving communication and collaboration within and across game development teams. Level design terminology is the set of terms and definitions used to describe the various elements of a game level, such as objectives, triggers, and assets. The importance of level design terminology lies in its ability to create a shared understanding among game developers, allowing them to communicate more effectively and work more efficiently. This thesis focuses on the level design terminology, exploring the blend of academic understanding (what we explicitly know) and practical expertise (what we've learned through experience). Specifically, we're focusing on how these two types of knowledge influence the language used by level designers.
