Furspeech (also known as Furspeak) is a furry form of constructed language based on the alteration of words and sentences of the established base language into its furry culture equivalents by substituting key vowels and syllables.
Wanderer submitted the term Furspeech, "The not-altogether-serious alteration of words into equivalents referring to the furry culture" to the Furry Dictionary on October 7, 2000, with the example "refurring" for referring.
Examples: "Persona" into "Fursona." "Someone" into "Somefur." "Perfect" into "Purrfect."
It can also take the form of substituting animal terms for comparable human terms, such as referring to a birthday as whelpday. This can also be done when the term in question is part of another word, e.g. a handkerchief becomes a pawkerchief, and holding one's head in one's hands becomes the far shorter facepaw.
