\\\"ardent love\\\"
\\\"an ardent lover\\\"
\\\"a fervent desire to change society\\\"
\\\"a fervent admirer\\\"
\\\"fiery oratory\\\"
\\\"an impassioned appeal\\\"
\\\"a torrid love affair\\\"

\\\"the fervent heat...merely communicated a genial warmth to their half-torpid systems\\\"
\\\"set out...when the fervid heat subsides\\\"
