Analysis of information sources in references of the Wikipedia article "Grok" in English language version.
In the 1949 short story "Venus and the Seven Sexes" by William Tenn, the author coined the term "griggo" as a Venusian basic sense describing intuitive understanding. Tenn used "griggo" as both a noun and a verb in phrases like "I griggoed his impatience." Over a decade later, acclaimed sci-fi author Robert Heinlein published his 1961 novel Stranger in a Strange Land, which introduced the word "grok" with a similar meaning of deep, empathetic comprehension. Heinlein's "grok" became hugely influential in 1960s counter-culture and lexicon. When asked if he was inspired by Tenn's prior "griggo," Heinlein admitted "It's possible, very possible."
