"Grok" means to understand something deeply and intuitively—not just intellectually, but in a way that becomes part of how you think and operate. It implies understanding something so thoroughly that you can predict its behavior and apply it naturally. The word originated in Robert Heinlein's 1961 sci-fi novel Stranger in a Strange Land, where it's a Martian concept meaning to drink or absorb. It's been adopted by programmers and tech culture to describe that moment when complex concepts suddenly click into place.
