The word "vibe" is a 20th-century clipping of "vibration," which entered English in the mid-17th century from Latin vibratio (a shaking, brandishing), itself from the verb vibrare (to shake, brandish, set in tremulous motion). The Latin root is traced back to the Proto-Indo-European root weip-, meaning "to turn, vacillate, tremble ecstatically." The semantic evolution from physical shaking to an intangible atmosphere is a metaphorical extension. In the 1960s, "vibes" (short for "vibrations") entered countercultural slang to describe intuitively felt emotional or spiritual emanations, which was then further shortened to the singular "vibe," now a mainstream term for an ambient feeling or mood.

The word "vibe" is a modern English shortening of the noun "vibration." As a simplex form, it is not productively segmented into smaller meaningful parts based on its current spelling.
