A staff with a metal tip that is used as a symbol of authority, often carried by certain officials or court officers.
The tipstaff was used by the bailiff to signify his authority in the courtroom.
Tipstaff → The word is formed from "tip" (from Old English *tipa*, meaning the end or point) and "staff" (from Old English *stæf*, meaning a stick or rod). A tipstaff originally referred to a staff with a pointed end, often used by officials or constables.
Think of the 'tip' as the pointed end of a 'staff' — that's why a tipstaff is a pointed staff used by officials.
