What does ardour mean?
Ardour is a noun denoting intense passion, fervent enthusiasm, or burning eagerness, whether directed at a cause, a creative pursuit, or another person. Derived from the Latin verb 'ardere', meaning to burn, the word literally frames emotion as fire — a metaphor that still shapes its connotations of heat, energy, and devotion. It appears most often in formal or literary contexts: one might speak of religious ardour, political ardour, or the ardour of new love. British English retains the spelling 'ardour', while American English uses 'ardor'; the two forms are otherwise identical in meaning and pronunciation. Because it suggests wholehearted, even consuming commitment, ardour is a useful word when ordinary words like 'interest' or 'liking' feel too weak. It can also carry a hint of excess — an ardour so intense it borders on recklessness — which gives writers a way to portray both admirable dedication and youthful imprudence within a single term.

Ardour comes from the Latin 'ardere', to burn — so when you feel ardour, you are literally described as being on fire with feeling.

Etymology of ardour
Ardour derives from the Latin 'ardor', meaning burning heat or blaze, from the verb 'ardere' (to burn). The word passed into Old French as 'ardour' and entered English in the Middle Ages, where it came to describe not physical fire but emotional intensity. Its Latin root also gives us 'ardent' and related words, all sharing the underlying image of fire as a symbol of passion.
How ardour is actually used
