I knew the Etymology of "grok", and shared it ...with my wife:
Robert A. Heinlein originally coined the term grok in his 1961 novel Stranger in a Strange Land as a Martian word that literally means "to drink", and had a much more profound figurative meaning that is hard for Earthlings to understand because of our assumption of a singular reality.
According to the book, drinking is a central focus on Mars where water is scarce. Martians use the merging of their bodies with water as a simple example or symbol of how two entities can combine to create a new reality greater than the sum of its parts. The water becomes part of the drinker, and the drinker part of the water. Both grok each other. Things that once had separate realities become entangled in the same experiences, goals, history, and purpose. Within the book, the statement of divine immanence verbalized between the main characters, "Thou Art God", is logically derived from the concept inherent in the term grok.
Heinlein describes Martian words as "guttural" and "jarring". Martian speech is described as sounding "like a bullfrog fighting a cat". Accordingly, grok is generally pronounced as a guttural "gr" terminated by a sharp "k" with very little or no vowel sound (a narrow IPA transcription might be [ɡɹ̩kʰ]).
