Etymology

Origin of ardor

1350–1400; Middle English < Latin, equivalent to ārd ( ēre ) to burn + -or -or ¹; replacing Middle English ardure < Old French ardur < Latin, as above; 17th century ardour < Anglo-French < Latin, as above

Explanation

Are you inspired to write love poems to your crush? Sprinkle rose petals in her path? Then you're feeling ardor — an intense kind of warmth and fervor most often associated with love. The Brits spell ardor with an extra vowel, so you'll often see this word written as ardour. But on either side of the pond it's a noun that brings to mind Pepe Le Pew and his fervent pursuit of the female species. But ardor isn't always about love. It's perfectly platonic to be "an ardent supporter" of a certain cause, or show eagerness and ardor in your approach to anything.
