Slang abounds in words of this description, immediate words, words created instantaneously no one knows either where or by whom, without etymology, without analogies, without derivatives, solitary, barbarous, sometimes hideous words, which at times possess a singular power of expression and which live. The executioner, le taule ; the forest, le sabri ; fear, flight, taf ; the lackey, le larbin ; the mineral, the prefect, the minister, pharos ; the devil, le rabouin . Nothing is stranger than these words which both mask and reveal. Some, le rabouin , for example, are at the same time grotesque and terrible, and produce on you the effect of a cyclopean grimace.
