>[!abstract] >To **grok** is a fictional Martian neologism coined by Robert A. Heinlein in his 1961 novel *A Stranger in a Strange Land*. It means to understand something so fully that the observer and the observed become one. It has since become lexicalized, especially within computer science and hacker culture, and in doing so has lost its quasi-mystical aspect to just mean "to deeply and intuitively understand" (hence X's naming of its Grok LLM). >[!related] >- **North** (upstream): — >- **West** (similar): — >- **East** (different): — >- **South** (downstream): —
