Syn.
– Fervor, Ardor. 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.
