Strong Language contributor Jonathon Green (@misterslang), the author of Green’s Dictionary of Slang, has a new project of special interest to SL readers: Slang Family Trees. “The aim,” writes Jonathon, “is to look at some of slang’s primary themes and show the way the lexis assesses given topics on a semantic basis.” The trees are constructed with mind-mapping software and appear as .pdf files. To get started, see vagina, penis, and drunk.
