nakatamisest

Could you clarify what "nakatamisest" refers to? It’s not a widely recognized term in English, and I want to ensure I draft an accurate, neutral wiki-style article. Is this an Estonian word meaning something like concealment or hiding (from a root verb nakatama/nakatamine), or does it denote a specific concept in a particular field (philosophy, linguistics, history, etc.)? If you provide a definition or context, I can write a concise article under 300 words. If you’d like, I can also propose a neutral stub for two common interpretations (concealment and forgetfulness) and tailor it once you choose.
