Passionate, fiery, impassioned, and fervent all show strong feeling, but the tone differs. Passionate is the most general, neutral word. Impassioned is formal, mainly for speeches. Fiery often suggests anger. Fervent stresses steady devotion or belief, not heat. Fiery's burning sense is not compared here.
