clime

The word 'clime' entered English in the late Middle English period, borrowed from the Latin clima, which itself originated from the Greek klima, meaning 'slope' or 'inclination'. This Greek term referred specifically to the slope of the earth from the equator to the poles, a concept used by ancient geographers to divide the world into latitudinal zones or regions characterized by their climate. Over time, the meaning shifted from the abstract geographical concept of a zone to a more poetic term for a region defined by its prevailing weather conditions. Thus, the modern, somewhat literary word 'clime' retains the ancient link between a geographic area and its atmospheric character.

The word is a simplex form derived from Latin clima, from Greek klima (meaning 'slope', 'region', 'zone of latitude').
