means A fermented paste of soybeans (often with rice, barley, or other grains) and koji mold, used to make soup, marinades, and sauces with a deep salty-savory flavor.

from From Japanese miso (味噌), written with characters that can suggest 'taste' plus a character for a kind of fermented bean relish. Its deeper roots are debated, but it's closely tied to Chinese fermented soybean pastes like jiang, which spread through East Asia long ago — each culture brewing its own version with local grains and local koji, miso being Japan's enduring take on that ancient fermentation craft.
