IPA: //ˈsɔːrɡəm//
KK: /ˈsɔrˌɡʌm/
A type of grain plant that is cultivated for food, animal feed, and biofuel, known for its drought resistance and ability to grow in poor soil.
Farmers often grow sourgum because it requires less water than other crops.
Sourgum originates from the combination of 'sour' (from Old English 'sūre', meaning having an acid taste) and 'gum' (from Old English 'goma', meaning a sticky substance). The word 'sourgum' refers to a type of tree known for its sour-tasting sap or gum.
Think of the 'sour' taste and the 'sticky substance' ('gum') to remember that 'sourgum' refers to a tree with a sour sap.
