Hooker.
Fervor is a boiling heat, and ardor is a burning heat. Hence, in metaphor, we commonly use fervor and its derivatives when we conceive of thoughts or emotions under the image of ebullition, or as pouring themselves forth. Thus we speak of the fervor of passion, fervid declamation, fervid importunity, fervent supplication, fervent desires, etc. Ardent is used when we think of anything as springing from a deepseated glow of soul; as, ardent friendship, ardent zeal, ardent devotedness; burning with ardor for the fight.
