Gostak
"Gostak", a meaningless noun, occurs in the phrase "the gostak distims the doshes", which exemplifies how it is possible to derive meaning from the syntax of a sentence even if the referents of the terms are entirely unknown. It is an example of a nonce word.
The phrase, coined in 1903 by Andrew Ingraham became popularised through its quotation in 1923 by C. K. Ogden and I. A. Richards in their book The Meaning of Meaning, and has since been referenced in a number of cultural contexts.
