frisson

The word 'frisson' entered English in the late 18th century, directly borrowed from French to capture a specific nuance of sensation. Its ultimate Latin ancestor is frigēre, meaning "to be cold," which connects to the Proto-Indo-European root srig-, also meaning "cold." The semantic journey is one of physical sensation evolving into emotional metaphor: from the literal physical shiver caused by cold, to the figurative shiver of excitement, fear, or intense pleasure. This elegant borrowing allows English to succinctly describe that sudden, involuntary thrill that runs through the body, preserving the vivid link between a physical chill and an emotional tremor.

The word is a direct loanword from French, where it functions as a simplex noun. It is derived from the Old French verb frissonner meaning "to shiver," which itself comes from the Vulgar Latin frictiōnem, a noun of action from the Latin verb frigēre meaning "to be cold."
