The first part of the word, "Lincombian," comes from the name of a made-up place where this language might be spoken. The second part, "Ranisian," could be the name of a person who came up with some of the words or rules for the language. Finally, "Jerzmanowician" might be a made-up surname or an adjective to describe something related to the language.
Overall, Lincombian-Ranisian-Jerzmanowician is just a fancy way of saying "a pretend language that some people might use for fun."
