Perfervid: intense emotion, full of intense emotion; ardent; zealous

Perfervid comes from the Latin word perfervidus, meaning very hot. In Latin, fervidus means glowing hot, or ardent. Adding per to the word only intensifies it.

The letters don’t need to be long, perfervid, or poetic. Just two, three, or four sentences that express what each person means to you.          – Michael Masterson in
