Kafib is five letters, two syllables, and opens with a hard K. The root 'kafi' appears in Arabic and related languages meaning 'sufficient' or 'enough', a word also embedded in the classical Sufi poetry form called kafi and in Hindustani music. The final B sharpens the ending and makes the whole string feel coined rather than borrowed, sitting somewhere between a proper name and a brand syllable.
