Origin of 'subzero'
The term 'subzero' is derived from Latin roots, where 'sub' means 'below' and 'zero' comes from the Greek word 'zephyrus' which refers to the concept of nothing, especially in temperature measurement. The usage of 'subzero' emerged primarily within the context of science and meteorology to describe temperatures that drop below the freezing point of water (0°C or 32°F). Over time, the term has become popular in everyday speech, particularly in regions experiencing harsh winter climates, as people express the extremes of cold weather conditions. The modern usage of 'subzero' can be traced back to the 20th century when it began to appear frequently in weather reports and discussions related to climate conditions.
