Salaams all... The name of the spear in Arabic is Rhoum. I believe it came from the word for long pointed leaf (Some say it is linked to the city name Rome).. When gunpowder began to take over that weapons role... the name passed to the long rifle also called the Abu Futtilla(the one with the match) or Jezail.
Rhoumi is, thus, the other word for the Arabian muzzle loading rifle.
