passion (n.)
Origin and meaning of passion
c. 1200, "the sufferings of Christ on the Cross; the death of Christ," from Old French passion "Christ's passion, physical suffering" (10c.), from Late Latin passionem (nominative passio) "suffering, enduring," from past-participle stem of Latin pati "to endure, undergo, experience," a word of uncertain origin. The notion is "that which must be endured."
The sense was extended to the sufferings of martyrs, and suffering and pain generally, by early 13c.
...
The specific meaning "intense or vehement emotion or desire" is attested from late 14c., from Late Latin use of passio to render Greek pathos "suffering," also "feeling, emotion."
German "Begeisterung" means "enthusiasm". (Not "fascination" as I always thought.)
But wait, Google Translate does show that one meaning of "begeistern" is "to fascinate". My paper German/English books don't even list that meaning. So I wonder why the noun "Begeisterung" wouldn't also mean fascination.
