Fervent means feeling and showing very strong belief. A fervent supporter, fervent prayer, fervent hope.
It is warm rather than angry and belongs to belief, hope and support rather than to opinion. The Latin means boiling, which is the image the word still carries: heat turned inward into conviction.
