Kiff

The name Kiff is a rare and somewhat enigmatic name with roots in Old English. It is believed to be a diminutive or a variant of names like Cynefrith or Cynewulf, where 'cyne' means 'royal' and 'frith' means 'peace' or 'wulf' means 'wolf'. However, a more direct and commonly cited etymology links it to the Old English word 'cyf', meaning 'bold' or 'brave'. This suggests a strong, assertive connotation from its earliest usage.

Its usage has been historically very limited, and it has never achieved widespread popularity. In modern times, it is most notably recognized through its association with the character Kiff Kroker from the animated television series 'Futurama', which has given it a small, niche recognition. Despite this, it remains a very uncommon name, often perceived as unique or quirky.
