Synonym discussion

Sense: adjective/2

All four words describe extreme heat, but they differ in emphasis and context. 'Tropical' (sense 2) connects the heat to the feeling of being in a hot, humid part of the world — it can be used literally or hyperbolically. 'Scorching' highlights the burning sensation on the skin and is very common in everyday speech ('a scorching afternoon'). 'Sweltering' focuses on the uncomfortable, sweaty feeling that comes from both heat and moisture ('a sweltering subway platform'). 'Blistering' is the most dramatic and often appears in sports or news contexts ('blistering sun'). For casual conversation, 'scorching' is the most flexible. For emphasising the discomfort of humidity, 'sweltering' works best. Example: 'It was a tropical heatwave, with scorching temperatures during the day and sweltering nights that offered no relief.'

Etymology

GreekLatinFrenchEnglish

The word 'tropical' comes from the Latin 'tropicus', which was borrowed from the Greek 'tropikos' (τροπικός), meaning 'of a turn' or 'related to a turning'. This root 'tropos' ('turn') refers to the turning of the Sun's path at the solstices — the points where the Sun appears to 'turn back' as it reaches its furthest north or south. The Tropic of Cancer and Tropic of Capricorn are named after the constellations that were in the sky at those turning points when the names were given. In English, 'tropical' started being used for the warm regions between these lines of latitude in the 16th century, and later broadened to describe anything extremely hot.
