Etymology: "Tokomaks" is simply the plural of "tokamak," a noun for a magnetic fusion chamber, a doughnut-shaped vessel in which a plasma is confined by strong magnetic fields so that atomic nuclei can be fused. The plural follows the regular English pattern of adding "-s" to a noun ending in "k," so there is nothing irregular to unpack in the form itself. The singular it belongs to is the more interesting story. "Tokamak" is a Russian coinage, an acronym built from the words for "toroidal chamber" and "magnetic coil," with the Russian forms of those terms run together into one word. The design it names was developed in the Soviet Union in the 1950s, and the word then passed into English largely through scientific writing in the decades that followed, as fusion research spread to laboratories around the world.
