noun / verb
rifle
RY-ful/ˈraɪfl/
A gun whose barrel has spiral grooves.
The rifle's barrel contains spiral grooves that distinguish it from a smoothbore gun.

Etymology
The gun-making verb probably comes from rifler, “to scratch or groove.” The firearm takes its name from spiral grooves cut inside its barrel, which spin the projectile and improve accuracy.
