Full of or characterized by fervor; passionate, intense, and enthusiastically zealous in feeling or expression.
From 'fervor' (Latin 'fervor', heat and passion) plus the adjectival suffix '-ous', which means 'full of' or 'characterized by' the quality in the root word.
Fervorous is rarer than fervent or fervid, but it has a wonderful quality—adding '-ous' to fervor creates this sense of being literally full of passionate heat, almost overflowing with it.
