Etymology: Sonchus is the Latin name for a genus of plants whose common names, sow-thistle and milk-thistle, come from the milky sap they exude when cut. The Greek word "sonchos" was used for these plants, and the Latin word "sonchus" was borrowed from it, so the name has been attached to the same plants for more than two thousand years. The genus was formalised within the Linnaean system of scientific naming, which gave each plant a Latin genus name, and that is where the word now mostly lives: in botanical texts rather than everyday speech. Its common relatives, the prickly sow-thistles and smooth sow-thistles, are familiar weeds in gardens and field edges, and their soft leaves have long been fed to pigs, rabbits, and poultry, which is how the "sow" in their names is usually explained.
