What is Ardor? 

The Latin word ardor originally meant the same as the French word ardor. It comes from the verb ardure, meaning ‘to burn’. In the fifteenth century, English first used ardor to describe a warmth that corresponds to passion or desire.

Old French ardure means heat, power, and Latin ador denotes a flame, fire, and burning.  

Those words were derived from the Latin verb ‘aridus’, a Proto-Indo-European verb meaning ‘to dry’ and ‘to burn’ and ‘to glow’. It is considered accurate in United States English. The word is not as prevalent as ‘ardour’.

Ardor is primarily used in the United States, while other parts of the world use ‘Ardour’ as the accurate spelling.  

The pronunciation is a bit different from its other spelling. However, they are both the same, have the same meaning. The only difference between them is that they are used in different regions and have different spellings. 

What is Ardour? 

Ardour is deemed accurate in Commonwealth English, the dialect spoken in England. It is common for some words in American English to end in -or and in British English to end in -our.

The French language’s ‘our’ ending corresponds to a different pronunciation than the ‘or’ sound. At first, Latin words were pronounced with a more ‘-ur’ sound, reflecting their spelling.

As a result, the pronunciation changed to the ‘-our’ ending in most. Many English words borrowed from French retained their spelling even if they weren’t pronounced the same way.

Even so, many English scholars deeply admired the Latin language, so much so that they imposed Latin restrictions on it, such as not ending sentences with propositions. 

This spelling is much more prevalent than ‘Ardor’ and is almost deemed accurate and used worldwide, other than the United States. However, the meaning is the same, and both the spelling are deemed accurate.
